Anomalous magnetoresistance behavior of CoFe nano-oxide spin valves at low temperatures

J. Ventura, J. B. Sousa, M. A. Salgueiro da Silva +2

We report magnetoresistance curves of CoFe nano-oxide specular spin valves of MnIr/CoFe/nano-oxidized CoFe/CoFe/Cu/CoFe/nano-oxidized CoFe/Ta at different temperatures from 300 to…
