Mechanism of Ferroelectricity in Perovskites - a Model Study
Paolo Barone, Sudipta Kanungo, Silvia Picozzi +1
By means of a model Hamiltonian approach we study the role of volume expansion, Hund's coupling and electron correlation in the standard hybridization mechanism for ferroelectricit…
Theoretical investigation of magnetoelectric effects in Ba2CoGe2O7
Kunihiko Yamauchi, Paolo Barone, Silvia Picozzi
A joint theoretical approach, combining macroscopic symmetry analysis with microscopic methods (density functional theory and model cluster Hamiltonian), is employed to shed light…
Buckling induced Zener polaron instability in half-doped manganites
Paolo Barone, Silvia Picozzi, Jeroen van den Brink
By calculating the electronic, orbital, magnetic and lattice structure of half-doped manganites we establish the central role of oxygen buckling caused by the tilting of the MnO$_6…
Strain effects on ferroelectric polarization and magnetism in orthorhombic HoMnO3
Diana Iuşan, Kunihiko Yamauchi, Paolo Barone +4
Aiming at increasing the ferroelectric polarization in AFM-E ortho-\hmo, we investigate the in-plane strain effects on both the magnetic configuration and the polarization by means…
