▼ [20a-W241-4] Giant tunnel magnetoresistance using a cation-disorder MgAl2O4(001) epitaxial barrier deposited by a direct sputtering technique
キーワード:Spintronics,MTJ,oxide
In this study, we present the acheivement of ~245% of TMR at RT using cation-disorder MgAl2O4-barrier based MTJs with Fe electrodes. The barriers were deposited with a direct sputtering technique which produced high crystalline quality and perfect lattice-matched interfaces.
