A giant planar Hall effect (PHE) and anisotropic magnetoresistance (AMR) is observed in TaP, a nonmagnetic Weyl semimetal with ultrahigh mobility. The perpendicular resistivity (i.e., the magnetic field applied normal to current) far exceeds zero-field resistivity, which thus rules out possible origin of negative longitudinal magnetoresistance. PHE/AMR finally attributed large orbital that stems from Furthermore, mobility-enhanced current jetting effects are found strongly deform line shape...
Besides the negative longitudinal magnetoresistance (MR), planar Hall effect (PHE) is a newly emerging experimental tool to test chiral anomaly or nontrivial Berry curvature in Weyl semimetals (WSMs). However, origins of PHE various systems are not fully distinguished and understood. Here we perform systematic study on anisotropic MR (AMR) Td-MoTe2, type-II WSM. Although AMR curves can be well fitted by theoretical formulas, demonstrate that resistivity arises from orbital (OMR), instead as...
Abstract The cross sections of state-selective charge exchange (CX) between highly charged ions and neutrals are important for modeling extreme ultraviolet soft X-ray emissions in many astrophysical objects with hot plasma impacting cold media. By using cold-target recoil-ion momentum spectroscopy, we measure O 6+ CX collisions He H 2 the collision energy range 19.5 to 100 keV amu −1 . relative single reported electron capture into 5+ (1 s nl ) n = 2, 3, 4, 5, ≥6 , respectively.

The mechanisms underlying the paramagnetic metal to insulator (PM-PI) and antiferromagnetic (PM-AFI) transitions in archetypical correlated oxide of ${\mathrm{V}}_{2}{\mathrm{O}}_{3}$ are long-standing yet not completely resolved topics condensed matter physics. Herein, utilizing large differences thermal expansion coefficient between ${\mathrm{Al}}_{2}{\mathrm{O}}_{3}$, a variation trigonal distortion continuous way is realized pure thin films grown on $c$-plane...
Abstract Astrophysical charge-exchange modeling depends on an accurate database of state-resolved and velocity-dependent cross sections. The sections, resolved by the quantum state with principal n orbital angular momentum ℓ , are pivotal in determining X-ray extreme ultraviolet (EUV) emissions following charge exchange between highly charged ions neutrals. However, current cross-sectional data primarily theoretically derived have undergone limited experimental validation. Using...
We report the discovery of superconductivity at $\ensuremath{\sim}9$ K in Fe${}_{1.05}$Te single crystals that have been exposed to air for more than six months. The is induced due oxygen incorporation and only exists surface layer samples. Our high-resolution transmission electron microscopy experiments density functional theory calculations show prefers locate interstitial site Fe-Te layer. X-ray photoelectron spectra characterize an enhancement itinerant character Fe $3d$ electrons, which...
The electronic structures of a representative rare earth monopnictide (i.e., DySb) under high magnetic field in the ferromagnetic state) are studied from both experimental and theoretical aspects. A non-saturated extremely large positive magnetoresistance (XMR) is observed (as as 3.7*10^4% at 1.8 K 38.7 T), along with Shubnikov-de Haas oscillations that well reproduced by our first principles calculations. Three possible origins XMR examined. Although band inversion found theoretically,...
The quasi-one-dimensional (quasi-1D) TaSe3 attracts considerable attention for its intriguing superconductivity and possible interplay with nontrivial topology charge density wave (CDW) state. However, unlike the isostructural analogues, CDW has not been observed despite quasi-1D character that is supposed to promote Peierls instabilities CDW. Here we synthesize mesowires (MWs) using a one-step approach. For MW of ~300 nm thick, distinct transition occurs at 65 K in resistivity measurement,...
Abstract State-resolved charge exchange (CX) cross sections are of the utmost importance for modeling related photon emissions existing in a broad range astrophysical environments. With cold-target recoil-ion momentum spectroscopy, we determined with high accuracy state-resolved single and double CX at quantum orbital angular level solar wind ion C 4+ collisions He an energy 1.67–20 keV u −1 , which allow one to benchmark calculations great detail, test applicability analytical n - ℓ...
The influence of growth rate and substrate temperature on the two-dimensional electron gas (2DEG) LaVO3/SrTiO3 interfaces has been investigated. It is found that both can modulate structural electrical properties through oxygen substrate-to-film transfer. When LaVO3 thin films are deposited at a low high rate, exhibit weak transfer resultant density vacancies in SrTiO3 substrate. As result, intrinsic effect (polar discontinuity and/or dielectric screening) dominates interfacial conduction,...
Acoustical properties of the sea bottom can be described using geoacoustic (GA) models. Most existing propagation models use GA parameters as properties. It is difficult to obtain for a layered because inter parameter coupling. These problems solved by inverting model-independent reflective P and Q. For multilayered bottom, sound field computation model, RamPQ, developed mapping (P, Q) spaces. The mean square error transmission loss in numerical simulations experimental data low-frequency...
