L-point quadrupole order under magnetic field in cubic PrIrZn
Hitoko Okanoya, Kazumasa Hattori
We study quadrupole orders in heavy-fermion compound PrIrZn under magnetic fields on the basis of the Landau theory. Assuming electric quadrupolar orders in the cu…
Purely Electronic Chirality without Structural Chirality
Takayuki Ishitobi, Kazumasa Hattori
We introduce the concept of purely electronic chirality (PEC), which arises in the absence of structural chirality. In condensed matter physics and chemistry, chirality has convent…
Probing magnetic-field-induced multipolar ordering through field-angle-resolved magnetostriction and thermal expansion in PrIrZn
Naoki Okamoto, Yohei Kono, Takahiro Onimaru +3
We performed field-angle-resolved magnetostriction and thermal-expansion measurements on PrIrZn, a cubic non-Kramers compound exhibiting antiferroquadrupolar order below…
Order parameter fluctuation effects on current-induced magnetization
Genta Furuya, Kazumasa Hattori
We investigate the impact of order parameter fluctuations on magnetoelectric effects in metallic systems using classical Monte Carlo simulations. We focus on a a chiral quadrupole…
Orbital moiré and quadrupolar triple-q physics in a triangular lattice
K. Hattori, T. Ishitobi, H. Tsunetsugu
We numerically study orders of planer type quadrupoles on a triangular lattice with nearest-neighbor isotropic and anisotropic interactions. This type of qua…
