Transport evidence of current-induced nematic Dirac valleys in a parity-time-symmetric antiferromagnet
H. Sakai, Y. Miyamoto, M. Kimata +6
Itinerant antiferromagnets with broken time-reversal symmetry have recently attracted attention, since their spin-split bands enable large magnetotransport responses comparable to…
Nonreciprocal charge transport in polar Dirac metals with tunable spin-valley coupling
M. Kondo, M. Kimata, M. Ochi +7
Nonreciprocal charge transport in solids, where resistance is different between rightward and leftward currents, is a key function of rectifying devices in the modern electronics,…
Magnetic excitations in the noncentrosymmetric magnet Sr2MnSi2O7
Masahiro Kawamata, Xiaoqi Pang, Hiroshi Murakawa +7
Magnetic excitations in the noncentrosymmetric magnet SrMnSiO were investigated through inelastic neutron scattering measurements. Major magnetic excitations are limite…
Magnetic structure of the noncentrosymmetric magnet Sr2MnSi2O7 through irreducible representation and magnetic space group analyses
Y. Nambu, M. Kawamata, X. Pang +6
Magnetic structures of the noncentrosymmetric magnet SrMnSiO were examined through neutron diffraction for powder and single-crystalline samples, as well as magnetometr…
