Large anomalous Hall effect and unusual domain switching in an orthorhombic antiferromagnetic material NbMnP
Hisashi Kotegawa, Yoshiki Kuwata, Vu Thi Ngoc Huyen +6
Specific antiferromagnetic (AF) spin configurations generate large anomalous Hall effects (AHEs) even at zero magnetic field through nonvanishing Berry curvature in momentum space.…
First-order phase transition to a nonmagnetic ground state in nonsymmorphic NbCrP
Yoshiki Kuwata, Hisashi Kotegawa, Hideki Tou +9
We report the discovery of a first-order phase transition at around 125 K in NbCrP, which is a nonsymmorphic crystal with Pnma space group. From the resistivity, magnetic susceptib…
Helimagnetic Structure and Heavy-Fermion-Like Behavior in the Vicinity of the Quantum Critical Point in MnP
H. Kotegawa, M. Matsuda, F. Ye +13
Antiferromagnet MnP with Neel temperature K is composed of Mn-tetrahedrons and zigzag chains formed by three inequivalent Mn sites. Due to the nearly frustrated lattic…
Magnetic correlations in the pressure-induced superconductor CrAs investigated by As nuclear magnetic resonance
Kei Matsushima, Hisashi Kotegawa, Yoshiki Kuwata +7
We report As-NMR results for CrAs under pressure, which shows superconductivity adjoining a helimagnetically ordered state. We successfully evaluated the Knight shift from t…
Superlattice formation lifting degeneracy protected by non-symmorphic symmetry through a metal-insulator transition in RuAs
Hisashi Kotegawa, Keiki Takeda, Yoshiki Kuwata +6
The single crystal of RuAs obtained by Bi-flux method shows obvious successive metal-insulator transitions at T_MI1~255 K and T_MI2~195$ K. The X-ray diffraction measurement reveal…
