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 La 0.7 Sr 0.3 MnO 3 (LSMO) is used as a source of spin pumping while the spin sink exhibiting the ISHE consists of SrRuO 3 (SRO). SRO is a ferromagnetic oxide with metallic conductivity, however, with a Curie temperature ( T C ) of 155 K, thus well below room temperature. This choice allows to perform the experiment above and below T C of the SRO and to demonstrate that SRO not only shows an ISHE of a magnitude comparable to Pt (though with opposite sign) in its non magnetic state but also exhibits a finite ISHE even 50 K below T C .
