Here, we present microscopic evidence of the persistence uniaxial A-type antiferromagnetic order to surface layers MnBi_{2}Te_{4} single crystals using magnetic force microscopy. Our results reveal termination-dependent contrast across both step edges and domain walls, which can be screened by thin soft magnetism. The robust is further corroborated observation spin-flop transitions, have been theoretically proposed decades ago. not only provide key ingredients for understanding electronic...
Antiferromagnetic (AFM) materials are a pathway to spintronic memory and computing devices with unprecedented speed, energy efficiency, bit density. Realizing this potential requires AFM simultaneous electrical writing reading of information, which also compatible established silicon-based manufacturing. Recent experiments have shown tunneling magnetoresistance (TMR) readout in epitaxial tunnel junctions. However, these TMR structures not grown using silicon-compatible deposition process,...
MoTe_{2} has recently attracted much attention due to the observation of pressure-induced superconductivity, exotic topological phase transitions, and nonlinear quantum effects. However, there been debate on intriguing structural transitions among various observed phases their connection underlying electronic properties. In this work, by means density-functional theory calculations, we investigate transition between polar T_{d} nonpolar 1T^{'} in reference a hypothetical high-symmetry T_{0}...
Under pressure, the semiconductor PbSnTe transitions from an insulator to a Weyl metal that displays large Berry curvature.
The polarization and piezoelectric response of the BiTe$X$ ($X$=Cl, Br, I) layered tellurohalides are computed from first principles. results confirm a mixed ionic-covalent character bonding, demonstrate that internal structure within each triple layer is only weakly affected by external stress, while changes in charge distribution with stress produce substantial negative response. This suggests new mechanism for should remain robust even ultra-thin film form this class materials.
Abstract The ability to control a magnetic phase with an electric field is of great current interest for variety low power electronics in which the state used either information storage or logic operations. Over past several years, there has been considerable amount research on pathways direction magnetization field. More recently, alternative pathway involving change (ferromagnet antiferromagnet) proposed. In this paper, we demonstrate Anomalous Hall Transport metamagnetic FeRh thin film,...
Rare-earth diantimondes exhibit coupling between structural and electronic orders, which are tunable under pressure temperature. Here we present the discovery of a new polymorph LaSb
In this paper, an economic cost model is proposed for processes integrating both automatic process control (APC) and statistical (SPC) quality monitoring control. Both the special cause common variations are reduced by applying integrated APC SPC. Traditionally, using SPC evaluated average run length (ARL). However, ARL may not be appropriate as a measurement of design since it does take into consideration variation. Also, there few studies that compare models such system effect parameters...
The Su-Schrieffer-Heeger model describes the soliton excitations in polyacetylene due to formation of antiphase domain walls from alternating bond pattern. topology two domains is characterized by trivial (0) and nontrivial ($\ensuremath{\pi}$) Zak phases, indicating a dimerization-dependent phase. Here, it demonstrated that pristine Bi also exhibits 0 $\ensuremath{\pi}$ phases depending on dimerization develops topological states at as three-dimensional analog model.
In order to explore the consequences of spin-orbit coupling on spin-phonon interactions in a set chemically-similar mixed metal oxides, we measured infrared vibrational properties Co$_4B_2$O$_9$ ($B$ = Nb, Ta) as function temperature and compared our findings with lattice dynamics calculations several different models coupling. Frequency vs. trends for Co$^{2+}$ shearing mode near 150 cm$^{-1}$ reveal significant shifts across magnetic ordering that are especially large relative terms....
Adaptive cumulative sum (ACUSUM) charts, which adjust the reference value dynamically based on estimated shift size, provide good performance in detecting a range of mean shifts. However, when is wide, ACUSUM may not perform well for small shifts over range. An adaptive runs rule, motivated by concept supplementary proposed, order to make control charts more sensitive The rule assigns scores consecutive size mean. chart supplemented with enhance its sensitivity average run length compared...
Multistage statistical process control (SPC) is an effective procedure for ensuring quality of products in multistage manufacturing processes. Effective SPC approaches monitoring and controlling processes are limited. Beta distributed data explained by input variables generally prevalent industries. In this paper, we propose a generalized linear model beta-distributed order to estimate the distribution parameters develop two control: they model-based charts beta regression model. The...
Similar to the univariate CUSUM chart, a multivariate (MCUSUM) chart can be designed detect particular size of mean shift optimally based on scheme sequential likelihood ratio test for noncentrality parameter. However, in case, probability is intractable mathematically and statistic does not have closed form expression which makes it impractical real application. We drive an approximate log-likelihood propose statistical process control χ2 change The properties proposed are explored. average...

ODP provides end-to-end guarantees to individual flows with minimal overhead, while keeping scalability characteristic of Diff-Serv. exercises per-flow admission control and bandwidth reservation at edge network only differentiates traffic classes in core network. In addition, adapt dynamically changing load, monitors utilization performs dynamic reconfiguration core. Through extensive simulations,...
Square-net tellurides host an array of electronic ground states and commonly exhibit charge-density-wave ordering. Here, we report the epitaxy DyTe2−δ on atomically flat MgO (001) using molecular beam epitaxy. The films are single phase highly oriented, as evidenced by transmission electron microscopy X-ray diffraction measurements. Epitaxial strain is evident in relieved thickness increases up to a value approximately 20 quintuple layers. Diffraction features associated with supercell...
The rare-earth ditellurides are known to form a two-dimensional square lattice where the strong Fermi surface nesting leads structural modulation. In contrast charge density waves, supercell modulation is accompanied by formation of periodic Te vacancy network, deficiency affects vector, i.e., size, via tuning chemical potential. this work, first-principles electronic-structure calculations for $\sqrt{5}\ifmmode\times\else\texttimes\fi{}\sqrt{5}$ supercell, which commonly appears in family...
