Microscopic model for magnetoelectric coupling through lattice distortions
(American Physical Society, 2019-10)
We propose a microscopic magnetoelectric model in which the coupling between spins and electric dipoles is mediated by lattice distortions. The magnetic sector is described by a spin S=1/2 Heisenberg model coupled directly ...
Influência do tamanho médio de grão nas propriedades ferroicas de compósitos magnetoelétricos particulados
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2016-04-08)
In the case of composites materials, which presents the magnetoelectric coupling,
there are so many questions about the influence of the microstructure on the coupled
and uncoupled properties. Thereby, this work proposes ...

Thickness dependence of the magnetoelectric coupling in Fe89Ga11 thin films deposited on ferroelectric PMN-PT single crystals
(Elsevier Science, 2020-05-01)
We have investigated the effects of applying an electric field on the dc and ac magnetic response of Fe89Ga11 thin films (t = 6 , 11, 17, 22, and 28 nm) that have been deposited on ferroelectric PMN-PT (011) and (001) ...
Evidence of magnetoelectric coupling on calcium doped bismuth ferrite thin films grown by chemical solution deposition
(American Institute of Physics (AIP), 2014-05-07)
Magnetoelectric coupling was observed at room temperature in calcium modified bismuth ferrite BiFeO3 (BFO) thin films deposited on Pt/TiO2/SiO2/Si (100) substrates by the chemical solution deposition. Undoped and Ca-doped ...
Magnetoelectric coupling of LaFeO3/BiFeO3 heterostructures
(2015-03-12)
BiFeO3 (BFO) and LaFeO3 (LFO) heterostructures were obtained at room temperature on Pt/TiO2/SiO2/Si (100) substrates by chemical solution deposition. The films were coherently grown at a temperature of 500°C for 2h. The ...

Angular dependence of the magnetoelectric effect in orthorhombic HoMnO3 films
(American Physical Society, 2011-12)
Epitaxial orthorhombic HoMnO3 films were grown on Nb-doped SrTiO3 (001) single-crystal substrates. X-ray diffractometry showed a uniform crystallographic orientation with the c axis along the substrate normal and an ...
Structure, ferroelectric/magnetoelectric properties and leakage current density of (Bi0.85Nd0.15)FeO3 thin films
(Elsevier B.V. Sa, 2011-04-28)
In this paper, we report on the structure, ferroelectric/magnetoelectric properties and improvement of leakage current density of (Bi0.85Nd0.15)FeO3 (BNFO) thin films deposited on Pt(1 1 1)/Ti/SiO2/Si substrates from the ...
