Exchange bias driven by the Dzyaloshinskii-Moriya interaction and ferroelectric polarization at G-type antiferromagnetic perovskite interfaces
Shuai Dong, Kunihiko Yamauchi, Seiji Yunoki +6
Exchange bias is usually rationalized invoking spin pinning effects caused by uncompensated antiferromagnetic interfaces. However, for compensated antiferromagnets other extrinsic…
Magnetically-induced ferroelectricity in orthorhombic manganites: microscopic origin and chemical trends
Kunihiko Yamauchi, Frank Freimuth, Stefan Blügel +1
The microscopic origin of the magnetically-driven ferroelectricity in collinear AFM-E orthorhombic manganites is explained by means of first-principles Wannier functions. We show t…
Interface effects at a half-metal/ferroelectric junction
Kunihiko Yamauchi, Biplab Sanyal, Silvia Picozzi
Magnetoelectric effects are investigated ab-initio at the interface between half-metallic and ferroelectric prototypes: Heusler CoMnSi and perovskite BaTiO. For the Co-term…
Dual nature of improper ferroelectricity in a magnetoelectric multiferroic
Silvia Picozzi, Kunihiko Yamauchi, Biplab Sanyal +2
Using first principles calculations, we study the microscopic origin of ferroelectricity (FE) induced by magnetic order in the orthorhombic HoMnO3. We obtain the largest ferroelect…
First-principles stabilization of an unconventional collinear magnetic ordering in distorted manganites
S. Picozzi, K. Yamauchi, G. Bihlmayer +1
First-principles calculations have been performed for different collinear magnetic orderings in orthorhombic manganites, such as HoMnO3, TbMnO3 and YMnO3, showing large GdFeO3-like…
Ab-initio electronic and magnetic structure in La_0.66Sr_0.33MnO_3: strain and correlation effects
Chunlan Ma, Zhongqin Yang, Silvia Picozzi
The effects of tetragonal strain on electronic and magnetic properties of strontium-doped lanthanum manganite, La_{2/3}Sr_{1/3}MnO_3 (LSMO), are investigated by means of density-fu…
