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 cond...

Sumario: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).
