Inverse spin Hall effect in a complex ferromagnetic oxide heterostructure.

We present spin pumping and inverse spin Hall effect (ISHE) in an epitaxial complex oxide heterostructure. Ferromagnetic La0.7Sr0.

Yttrium Iron Garnet Thin Films with Very Low Damping Obtained by Recrystallization of Amorphous Material.

We have investigated recrystallization of amorphous Yttrium Iron Garnet (YIG) by annealing in oxygen atmosphere. Our findings show that well below the melting temperature the material transforms into a fully epitaxial layer with exceptional quality, both structural and magnetic. In ferromagnetic resonance (FMR) ultra low damping and extremely narrow linewidth can be observed.

Valence band offset at the Si/SiSn interface by applying deep level transient spectroscopy.

A set of Si1-x Sn x /Si(001) quantum wells (QWs) is grown by applying molecular beam epitaxy. The activation energies of holes in these QWs are studied by deep-level transient spectroscopy. It is observed that the holes activation energies increase monotonically with the Sn fraction (x).

Interface Reactions in LSMO-Metal Hybrid Structures.

Perovskites form a class of promising materials for the development of multifunctional devices but require reliable strategies for forming electrical contacts without compromising functionality. We explore the interactions of a range of metal contacts with ferromagnetic oxide La0.7Sr0.
