Spin Conductivity Based on Magnetic Toroidal Quadrupole Hidden in Antiferromagnets
Satoru Hayami, Megumi Yatsushiro
We report our theoretical results on spin conductivity in antiferromagnets by focusing on the role of the magnetic toroidal quadrupole (MTQ) in electron systems. The MTQ is charact…
Multipole classification in 122 magnetic point groups for unified understanding of multiferroic responses and transport phenomena
Megumi Yatsushiro, Hiroaki Kusunose, Satoru Hayami
Mutual interplay between the electronic degrees of freedom in solids, such as charge, spin, orbital, sublattice, and bond degrees of freedom, is a source of cross-correlated phenom…
NQR and NMR spectra in odd-parity multipole material CeCoSi
Megumi Yatsushiro, Satoru Hayami
We theoretically study NQR and NMR spectra in the presence of odd-parity multipoles originating from staggered antiferromagnetic and antiferroquadrupole orderings. For the -elec…
Odd-Parity Multipoles by Staggered Magnetic Dipole and Electric Quadrupole Orderings in CeCoSi
Megumi Yatsushiro, Satoru Hayami
We investigate a possibility of odd-parity multipole orderings in a locally noncentrosymmetric tetragonal compound CeCoSi. By performing symmetrical and microscopic mean-field anal…
Atomic-Scale Magnetic Toroidal Dipole under Odd-Parity Hybridization
Megumi Yatsushiro, Satoru Hayami
Magnetic toroidal dipole (MTD) is one of a fundamental constituent to induce magneto-electric effects in the absence of both spatial inversion and time-reversal symmetries. We repo…
Classification of atomic-scale multipoles under crystallographic point groups and application to linear response tensors
Satoru Hayami, Megumi Yatsushiro, Yuki Yanagi +1
Four types of atomic-scale multipoles, electric, magnetic, magnetic toroidal, and electric toroidal multipoles, give a complete set to describe arbitrary degrees of freedom for cou…
