Substitution effects in RuO single crystals
Shubhankar Paul, Kunihiko Yamauchi, Shogo Yamashita +7
RuO has emerged as one of the leading candidates for investigating altermagnetism. Recent quantum oscillation and angle-resolved photoemission spectroscopy measurements found t…
Two Microscopic Mechanisms of Piezomagnetism in CoF from First-Principles Calculations
Hiroshi Katsumoto, Tamio Oguchi, Kunihiko Yamauchi
Rutile-structured CoF has long been recognized as a prototypical piezomagnetic material. Recently, it has attracted renewed interest as an altermagnet, exhibiting spin-split el…
Interplay of Magnetic Order, Structural Stability, and Orbital Ordering in BaFe2X3 (X = S and Se)
Kunihiko Yamauchi, Takuya Aoyama, Kenya Ohgushi
BaFe2X3 (X= S and Se) are quasi-one-dimensional Mott insulators with a ladder structure that exhibit Stripe- and Block-type antiferromagnetic order, respectively. The ladder arrang…
Phonon-driven tuning of exchange interactions in Y3Fe5O12
Kunihiko Yamauchi, Tamio Oguchi
Yttrium iron garnet (Y3Fe5O12) is a prototypical ferrimagnetic insulator widely used in spin-wave and magnonic devices owing to its extremely low magnetic damping and long magnon p…
Quantum anomalous Hall effect in monolayer transition-metal trihalides
Thi Phuong Thao Nguyen, Kunihiko Yamauchi
We present systematic first-principles results for the electronic and magnetic properties of two-dimensional transition-metal trihalide monolayers MX3 (M = V, Cr, Mn, Fe, Ni, Pd; X…
Fermi-liquid behavior and characteristic temperature-dependent susceptibility in clean RuO crystal
Shubhankar Paul, Atsutoshi Ikeda, Hisakazu Matsuki +6
The magnetic nature of the altermagnet candidate RuO remains under debate. It has been recently shown from quantum oscillations and angle-resolved photoemission spectroscopy (A…
