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…
Ab initio prediction of anomalous Hall effect in antiferromagnetic CaCrO
Thi Phuong Thao Nguyen, Kunihiko Yamauchi
While the anomalous Hall effect takes place typically in ferromagnets with finite magnetization, large anomalous Hall conductivity in noncollinear antiferromagnetic systems has bee…
Hydrogen-Induced Metal-Insulator Transition Accompanied by Inter-Layer Charge Ordering in SmNiO
Kunihiko Yamauchi, Ikutaro Hamada
The microscopic mechanism of the hydrogen-induced metal-insulator transition in SmNiO is clarified by means of density-functional theory with the Hubbard U correction. While 10…
Microscopic origin of magnetism in monolayer transition metal dihalides
Kira Riedl, Danila Amoroso, Steffen Backes +7
Motivated by the recent wealth of exotic magnetic phases emerging in two-dimensional frustrated lattices, we investigate the origin of possible magnetism in the monolayer family of…
Origin of magnetovolume effect in a cobaltite
Ping Miao, Zhijian Tan, Sanghyun Lee +21
The layered perovskite PrBaCo2O5.5+x demonstrates a strong negative thermal expansion (NTE) which holds potential for being fabricated into composites with zero thermal expansion.…
Bulk Rashba Effect in Multiferroics: a theoretical prediction for BiCoO3
Kunihiko Yamauchi, Paolo Barone, Silvia Picozzi
We put forward the concept of a bulk Rashba effect emerging in a multiferroic material, such as an antiferromagnetic system with a polar crystal structure. According to symmetry co…
