Electron energy loss spectroscopy determination of Ti oxidation state at the (001) LaAlO3/SrTiO3 interface as a function of LaAlO3 growth conditions
Jean-Luc Maurice, Gervasi Herranz, Christian Colliex +10
At the (001) interface between the two band-insulators LaAlO3 and SrTiO3, a high-mobility electron gas may appear, which has been the object of numerous works over the last four ye…
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…
Mapping the Spatial Distribution of Charge Carriers in LaAlO3/SrTiO3 Heterostructures
M. Basletic, J. -L. Maurice, C. Carretero +7
At the interface between complex insulating oxides, novel phases with interesting properties may occur, such as the metallic state reported in the LaAlO3/SrTiO3 system. While this…
High Mobility in LaAlO3/SrTiO3 Heterostructures: Origin, Dimensionality and Perspectives
G. Herranz, M. Basletic, M. Bibes +9
We have investigated the dimensionality and origin of the magnetotransport properties of LaAlO3 films epitaxially grown on TiO2-terminated SrTiO3(001) substrates. High mobility con…
