Nature of the magnetoelectric coupling in multiferroic Pb(Fe(1/2)Nb(1/2))O(3) ceramics
(Amer Physical Soc, 2008-08-01)
In this work, electrical permittivity measurements in lead iron niobate (PFN) ceramics were performed in the frequency and temperature ranges from 10 kHz to 1.2 GHz and from 15 to 450 K, respectively. the microwave dielectric ...
Design an implementation of a system for magnetoelectric measurements on BiFeO3 nanoparticles as a function of temperature and magnetic field
(UniandesIngeniería ElectrónicaFacultad de IngenieríaDepartamento de Ingeniería Eléctrica y Electrónica, 2019)
"The magnetoelectric effect (ME), the appearance of a dc bias voltage in the presence of an ac magnetic field, present in multiferroic materials attracts much attention since it allows for a novel way to couple electric ...
Monte Carlo simulation of charge mediated magnetoelectricity in multiferroic bilayers
(2014-12-01)
Simulations of a bilayer ferroelectric/ferromagnetic multiferroic system were carried out, based on the Monte
Carlo method and Metropolis dynamics. A generic model was implemented with a Janssen-like Hamiltonian,
taking ...
Phonons and hybrid modes in the high and low temperature far infrared dynamics of hexagonal TmMnO3
(IOP Publishing, 2014-06)
We report on temperature dependent TmMnO3 far infrared emissivity and reflectivity spectra from 1910K to 4K. At the highest temperature the number of infrared bands is lower than that predicted for centrosymmetric P63/mmc ...
Materiais e técnicas para nanoestruturas magnetoelétricas compósitas
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2014-12-19)
Hybrid nanostructures which integrate two or more technologically interesting physical properties are
fundamental for developing new generations of electronic devices. Exhibiting at least two coupled ferroic orders,
multiferroics ...
