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…
Dislocation-induced flexoelectricity in SrTiO 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-HfTe
Y. Nakata, K. Sugawara, A. Chainani +9
We have performed angle-resolved photoemission spectroscopy on transition-metal dichalcogenide 1-HfTe to elucidate the evolution of electronic states upon potassium (K) depo…
Band splitting and Weyl nodes in trigonal tellurium studied by angle-resolved photoemission spectroscopy and density functional theory
K. Nakayama, M. Kuno, K. Yamauchi +5
We have performed high-resolution angle-resolved photoemission spectroscopy (ARPES) on trigonal tellurium consisting of helical chains in the crystal. Through the band-structure ma…
Quantum Oscillations of the Metallic Triangular-lattice Antiferromagnet PdCrO2
Jong Mok Ok, Y. J. Jo, K. Kim +6
We report the de Haas-van Alphen (dHvA) oscillations and first-principle calculations for triangular antiferromagnet PdCrO2 showing unconventional anomalous Hall effect (AHE). The…
