Quantitative study of the spin Hall magnetoresistance in ferromagnetic insulator/normal metal hybrids
Quantitative study of the spin Hall magnetoresistance in ferromagnetic insulator/normal metal hybrids
We experimentally investigate and quantitatively analyze the spin Hall magnetoresistance effect in ferromagnetic insulator/platinum and ferromagnetic insulator/nonferromagnetic metal/platinum hybrid structures. For the ferromagnetic insulator, we use either yttrium iron garnet, nickel ferrite, or magnetite and for the nonferromagnet, copper or gold. The spin Hall magnetoresistance effect is theoretically ascribed to …
