Two Microscopic Mechanisms of Piezomagnetism in CoF $_{2}$ from First-Principles Calculations

Hiroshi Katsumoto, Tamio Oguchi, Kunihiko Yamauchi

Rutile-structured CoF $_{2}$ has long been recognized as a prototypical piezomagnetic material. Recently, it has attracted renewed interest as an altermagnet, exhibiting spin-split el…

Dislocation-induced flexoelectricity in SrTiO $_{3}$ nanostructure from first principles

Kunihiko Yamauchi, Thi Phuong Thao Nguyen, Tamio Oguchi

Flexoelectricity refers to a linear coupling between the electric polarization and the strain gradient, such as bending or asymmetric compression. This effect is enhanced in nano-s…

Dimensionality reduction and band quantization induced by potassium intercalation in 1 $T$ -HfTe $_{2}$

Y. Nakata, K. Sugawara, A. Chainani +9

We have performed angle-resolved photoemission spectroscopy on transition-metal dichalcogenide 1 $T$ -HfTe $_{2}$ to elucidate the evolution of electronic states upon potassium (K) depo…
