Mechanisms of exchange bias with multiferroic BiFeO3 epitaxial thin films
H. Bea, M. Bibes, F. Ott +7
We have combined neutron scattering and piezoresponse force microscopy to study the relation between the exchange bias observed in CoFeB/BiFeO3 heterostructures and the multiferroi…
Fractal dimension and size scaling of domains in thin films of multiferroic BiFeO3
G. Catalan, H. Bea, S. Fusil +4
We have analyzed the morphology of ferroelectric domains in very thin films of multiferroic BiFeO3. Unlike the more common stripe domains observed in thicker films BiFeO3 or in oth…
Unravelling the origin of the controversial magnetic properties of BiFeO3 thin films
Helene Bea, Manuel Bibes, Eric Jacquet +3
Single phase (001)-oriented BiFeO3 (BFO) thin films grown by pulsed laser deposition can only be obtained in a narrow window of deposition pressure and temperature and have a low m…
Combining half-metals and multiferroics into epitaxial heterostructures for spintronics
H. Bea, M. Bibes, M. Sirena +8
We report on the growth of epitaxial bilayers of the La2/3Sr1/3MnO3 (LSMO) half-metallic ferromagnet and the BiFeO3 (BFO) multiferroic, on SrTiO3(001) by pulsed laser deposition. T…
Influence of parasitic phases on the properties of BiFeO3 epitaxial thin films
H. Bea, M. Bibes, A. Barthelemy +10
We have explored the influence of deposition pressure and temperature on the growth of BiFeO3 thin films by pulsed laser deposition onto (001)-oriented SrTiO3 substrates. Single-ph…
