Metallic elements having negative enthalpies of mixing tend to form characteristic local atomic clusters. In this review, we use the structural information in first nearest neighbour shell level, or first-shell cluster, derive composition rules two types complex alloy phases, quasicrystals and bulk metallic glasses, both being composed with mixing. We show phenomena quasicrystal-forming systems, where major such as cluster line, electron concentration size criteria are derived. Then analyse...
We report electric field control of the interfacial Dzyaloshinskii-Moriya interaction (DMI) in MgO/Fe/Pt multilayers. The DMI is obtained and quantified by Brillouin light scattering measurements based on frequency nonreciprocity spin waves a ferromagnet. magnitude induced found to linearly increase as function intensity. efficiency characterized ratio energy change field, which be equal 67 fJ/(Vm) with positive field. further demonstrate that origin enhanced results from MgO/Fe interface....
We investigate the orbital torque generated in ferromagnetic (FM)/manganese (Mn) bilayer systems based on angular-dependent spin-torque resonance (ST-FMR) experiments. From ST-FMR results, it is found that a relatively large out-of-plane anti-damping can be obtained Ni/Mn bilayers. The Gilbert damping constant, derived from resonant linewidth of frequency-dependent experiments, decreases almost linearly with increasing thickness Mn, further indicating systems. origin this attributed to...
The inter-grain exchange-coupling interactions, effective anisotropy, and coercivity in nanocomposite Nd2Fe14B/α−Fe magnets were investigated. anisotropy of has been calculated starting from the statistics boundaries between magnetically hard-hard, hard-soft, soft-soft grains. result shows that decreases with reduction grain size and/or increase soft phase components. When sizes reduce to 4–5 nm, Keff 1/3−1/4 ordinary value K. demonstrates a similar behavior. decrement is mainly due...
Abstract First‐principles LDA + U calculations have been performed to study the effects of oxygen vacancies (V O ) on electronic structure and magnetism in undoped rutile TiO 2– x . Instead treated as an adjustive parameter, value was determined by constrained‐density‐functional calculations. The calculated reveals that valence electrons released V would occupy mainly neighboring Ti:3d orbital which then becomes spin‐polarized due intra‐atomic exchange interaction, thereby giving rise...

The Dzyaloshinskii-Moriya interaction (DMI) is a very interesting phenomenon for creating devices to exploit spin chirality, but enhancing DMI in artificial structures still challenging. This comprehensive investigation presents several possible approaches manipulating interfacial magnetic multilayers. These results are expected facilitate the engineering of large spintronic applications.
Well-dispersed Ag nanoparticles (NPs) are successfully decorated on Fe 3 O 4 @SiO 2 nanorods (NRs) via a facile step-by-step strategy. This method involves coating α -Fe NRs with uniform silica layer, reduction in 10% H /Ar atmosphere at 450°C to obtain NRs, and then depositing NPs the surface of through sonochemical step. It was found that as-prepared Ag-decorated magnetic (Ag-MNRs) exhibited higher catalytic efficiency than bare degradation organic dye could be easily recovered by...
The interfacial Dzyaloshinskii-Moriya interaction (i-DMI) has been exploited in as-made symmetrical Au/[Fe/Au]n structures. By tailoring the chirality of i-DMI at Au/Fe interface, an overall enhancement can be obtained such a structure. Furthermore, tunability was realized by changing stacking number n. Compared to top Fe, large tensile stress bottom Fe due lattice mismatch responsible for change sub/Au/Fe system. Layer-resolved DMI calculations revealed that sign spin-orbit coupling (SOC)...
The low Gilbert damping factor, which is usually measured by ferromagnetic resonance, crucial in spintronic applications. Two-magnon scattering occurs when the orthogonality of resonance mode and other degenerate spin wave modes was broken magnetic anisotropy, voids, second phase, surface defects, etc., important analysis linewidth. Direct fitting to linewidth with advisable only a linear function measuring frequency broad band measurement. We observe nonlinear Co2MnSi thin films respect...
Co2MnSi thin films are made by magnetron sputtering onto MgO (001) substrates. The crystalline quality is improved increasing depositing temperature and/or annealing temperature. sample deposited at 550°C and subsequently annealed (sample I) exhibits a pseudo-epitaxial growth with partially ordered L21 phase. Sample I shows four-fold magnetic anisotropy, in addition to relatively weak uniaxial anisotropy. Gilbert damping factor of smaller than 0.001, much reported ones. possible reasons...
High spin states of the odd proton-nucleus 169Ta have been populated in reaction 155Gd(19F,5n) with beam energies 97 MeV. Rotational band based on d3/2 proton 1/2[411] Nilsson state has pushed up to 39/2+ α = 1/2 decay sequence. Its signature partner, -1/2 sequence four link transitions established and was reassigned be a semi-decoupled band. The systematics splitting K bands rear-earth region accidental degeneracy conclusion given by angular projection shell model were discussed.
