Room temperature magnetoresistance in CoFeB/SrTiO{sub 3}/CoFeB magnetic tunnel junctions deposited by ion beam sputtering

Room temperature transport properties are reported in polycrystalline SrTiO{sub 3}-based magnetic tunnel junctions deposited by ion beam sputtering. The junctions comprise CoFeB electrodes and the SrTiO{sub 3} barrier with thickness varied between 0.9 and 1.9 nm. Resistance area product values betwe...
