Observation of quantum oscillations near the Mott-Ioffe-Regel limit in CaAs3
Yuxiang Wang, Minhao Zhao, Jinglei Zhang +24
The Mott-Ioffe-Regel limit sets the lower bound of carrier mean free path for coherent quasiparticle transport. Metallicity beyond this limit is of great interest because it is oft…
Purity-dependent Lorenz number, electron hydrodynamics and electron-phonon coupling in WTe
Wei Xie, Feng Yang, Liangcai Xu +3
We present a study of electrical and thermal transport in Weyl semimetal WTe down to 0.3 K. The Wiedemann-Franz law holds below 2 K and a downward deviation starts above. The d…
High-field immiscibility of electrons belonging to adjacent twinned bismuth crystals
Yuhao Ye, Akiyoshi Yamada, Yuto Kinoshita +16
Bulk bismuth has a complex Landau spectrum. The small effective masses and the large g-factors are anisotropic. The chemical potential drifts at high magnetic fields. Moreover, twi…
Fabrication-induced even-odd discrepancy of magnetotransport in few-layer MnBiTe
Yaoxin Li, Yongchao Wang, Zichen Lian +20
The van der Waals antiferromagnetic topological insulator MnBi2Te4 represents a promising platform for exploring the layer-dependent magnetism and topological states of matter. Rec…
Tuning the anomalous Nernst and Hall effects with shifting the chemical potential in Fe-doped and Ni-doped CoSnS
Jie Liu, Linchao Ding, Liangcai Xu +3
CoSnS is believed to be a magnetic Weyl semimetal. It displays large anomalous Hall, Nernst and thermal Hall effects with a remarkably large anomalous Hall angle. Here,…
Magnetostriction, piezomagnetism and domain nucleation in a kagome antiferromagnet
Qingkai Meng, Jianting Dong, Pan Nie +9
Whenever the elastic energy of a solid depends on magnetic field, there is a magnetostrictive response. Field-linear magnetostriction implies piezomagnetism and vice versa. Here, w…
Quantum oscillations, Magnetic breakdown and thermal Hall effect in CoSnS
Linchao Ding, Jahyun Koo, Changjiang Yi +7
CoSnS is a ferromagnetic semi-metal with Weyl nodes in its band structure and a large anomalous Hall effect below its Curie temperature of 177 K. We present a detailed…
Planar Hall effect caused by the memory of antiferromagnetic domain walls in MnGe
Liangcai Xu, Xiaokang Li, Linchao Ding +2
In MnX (X=Sn, Ge) antiferromagnets domain walls are thick and remarkably complex because of the non-collinear arrangement of spins in each domain. A planar Hall effect (PHE), a…
Thermal conductivity of bulk InO single crystals
Liangcai Xu, Benoit Fauqué, Zengwei Zhu +3
The transparent semiconductor InO is a technologically important material. It combines optical transparency in the visible frequency range and sizeable electric conduct…
Anomalous transverse response of CoMnGa and universality of the room-temperature ratio across topological magnets
Liangcai Xu, Xiaokang Li, Linchao Ding +6
The off-diagonal (electric, thermal and thermoelectric) transport coefficients of a solid can acquire an anomalous component due to the non-trivial topology of the Bloch waves. We…
Strong Pauli paramagnetic effect in the upper critical field of KCaFeAsF
Teng Wang, Chi Zhang, Liangcai Xu +11
Recently, 12442 system of Fe-based superconductors has attracted considerable attention owing to its unique double-FeAs-layer structure. A steep increase in the in-plane upper crit…
Intrinsic anomalous Nernst effect amplified by disorder in a half-metallic semimetal
Linchao Ding, Jahyun Koo, Liangcai Xu +9
Intrinsic anomalous Nernst effect (ANE), like its Hall counterpart, is generated by Berry curvature of electrons in solids. Little is known about its response to disorder. In contr…
Magnetic exchange induced Weyl state in a semimetal EuCd2Sb2

Magnetic Weyl semimetals (WSMs) bearing long-time pursuing are still very rare. We herein identified magnetic exchange induced Weyl state in EuCd2Sb2, a semimetal in type IV magnet…
Chiral domain walls of MnSn and their memory
Xiaokang Li, Clément Collignon, Liangcai Xu +8
Magnetic domain walls are topological solitons whose internal structure is set by competing energies which sculpt them. In common ferromagnets, domain walls are known to be of eith…
Finite-temperature violation of the anomalous transverse Wiedemann-Franz law
Liangcai Xu, Xiaokang Li, Xiufang Lu +7
The Wiedemann-Franz (WF) law links the ratio of electronic charge and heat conductivity to fundamental constants. It has been tested in numerous solids, but the extent of its relev…
