Competing misfit relaxation mechanisms in epitaxial correlated oxides
Felip Sandiumenge, José Santiso, Lluis Balcells +4
Strain engineering of functional properties in epitaxial thin films of strongly correlated oxides exhibiting octahedral-framework structures is hindered by the lack of adequate mis…
Mn valence instability in La2/3Ca1/3MnO3 thin films
S. Valencia, A. Gaupp, W. Gudat +5
A Mn valence instability on La2/3Ca1/3MnO3 thin films, grown on LaAlO3 (001)substrates is observed by x-ray absorption spectroscopy at the Mn L-edge and O K-edge. As-grown samples,…
Exchange bias in laterally oxidized Au/Co/Au nanopillars
Ll. Balcells, B. Martinez, O. Iglesias +6
Au/Co/Au nanopillars fabricated by colloidal lithography of continuous trilayers exhibit and enhanced coercive field and the appearance of an exchange bias field with respect to th…
Magnetic dead layers in La2/3Ca1/3MnO3 thin films probed by X-ray magnetic circular dichroism in reflection
S. Valencia, A. Gaupp, W. Gudat +3
Surface magnetic properties of perovskite manganites have been a recurrent topic during last years since they play a major role in the implementation of magnetoelectronic devices.…
Formation of Mn2+ in La2/3Ca1/3MnO3 Thin Films due to Air Exposure
S. Valencia, A. Gaupp, Ll. Abad +5
We report on the chemical stability of La2/3Ca1/3MnO3 thin films. X-ray absorption spectroscopy at the Mn L-edge and O K-edge makes evident deviations from the nominally expected (…
Evidence of strong antiferromagnetic coupling between localized and itinerant electrons in ferromagnetic Sr2FeMoO6
M. Tovar, M. T. Causa, A. Butera +4
Magnetic dc susceptibility () and electron spin resonance (ESR) measurements in the paramagnetic regime, are presented. We found a Curie-Weiss (CW) behavior for (T) with a fe…
