Record-High Proximity-Induced Anomalous Hall Effect in (BiSb)2Te Thin Film Grown on CrGeTe Substrate
Xiong Yao, Bin Gao, Myung-Geun Han +6
Quantum anomalous Hall effect(QAHE) can only be realized at extremely low temperatures in magnetically doped topological insulators(TIs) due to limitations inherent with the doping…
Spin-Liquid-Like State in Pure and Mn-Doped TbInO3 with Nearly Triangular Lattice
M. G. Kim, B. Winn, S. Chi +8
Inelastic neutron scattering studies in single crystals of TbInO3 and TbIn0.95Mn0.05O3 with nearly-triangular antiferromagnetic lattice are reported. At low energies, a broad and a…
Soft antiphase tilt of oxygen octahedra in the hybrid improper multiferroic Ca3Mn1.9Ti0.1O7
Feng Ye, Jinchen Wang, Jieming Sheng +13
We report a single crystal neutron and x-ray diffraction study of the hybrid improper multiferroic Ca3Mn1.9Ti0.1O7 (CMTO), a prototypical system where the electric polarization ari…
High-temperature terahertz optical diode effect without magnetic order in polar FeZnMoO
Shukai Yu, Bin Gao, Jae Wook Kim +5
We present a terahertz spectroscopic study of polar ferrimagnet FeZnMoO. Our main finding is a giant high-temperature optical diode effect, or nonreciprocal directional dic…
Successive magnetic field-induced transitions and colossal magnetoelectric effect in NiTeO
Jae Wook Kim, S. Artyukhin, E. D. Mun +8
We report the discovery of a metamagnetic phase transition in a polar antiferromagnet NiTeO that occurs at 52 T. The new phase transition accompanies a colossal magnetoelec…
Partially disordered antiferromagnetism and multiferroic behavior in a frustrated Ising system, CoCl-2SC(NH)
Eundeok Mun, Dagmar Franziska Weickert, Jaewook Kim +6
We investigate partially disordered antiferromagnetism in CoCl-2SC(NH), in which a-b plane hexagonal layers are staggered along the c-axis, rather than stacked. A robus…
55~Tesla coercive magnetic field in frustrated SrNiIrO
John Singleton, Jae Wook Kim, Craig V. Topping +8
We have measured extremely large coercive magnetic fields of up to 55~T in SrNiIrO, with a switched magnetic moment per formula unit. As far as we a…
Multiferroicity with coexisting isotropic and anisotropic spins in CaCoMnO
Jae Wook Kim, Y. Kamiya, E. D. Mun +9
We study magnetic and multiferroic behavior in CaCoMnO (0.97) by high-field measurements of magnetization (), magnetostriction (()/), elec…
Pauli-limiting effects in the upper critical fields of a clean LiFeAs single crystal
Seunghyun Khim, Bumsung Lee, Jae Wook Kim +3
We have investigated the temperature-dependence of the upper critical field Hc2(T) in a LiFeAs single crystal by direct measurements of resistivity under static magnetic fields up…
Nearly isotropic upper critical fields in a SrFeCoAs single crystal
Seunghyun Khim, Jun Sung Kim, Jae Wook Kim +4
We study temperature dependent upper critical field of a SrFeCoAs single crystal (\textit{T}=20.2 K) along \textit{ab}-plane and \textit{c}…
Evidence for dominant Pauli paramagnetic effect in the upper critical fields of a FeTe0.6Se0.4 superconductor
Seunghyun Khim, Jae Wook Kim, Eun Sang Choi +4
We investigate temperature-dependence of the upper critical fields Hc2(T) of a superconducting FeTe0.6Se0.4 single crystal by measuring resistivity in static magnetic fields up to…
