[13a-2J-2] Enhancement of coercive force of spinel/Cr/Fe multilayers and Cr thickness dependence
Keywords:spintronics,spinel ferrite
To develop spintronic devices, the magnetization process is an important issue. Although the interlayer exchange coupling (IEC) was known in the metallic system, there are few papers about the magnetic coupling in the multilayer including oxide layer. Therefore, we studied about magnetic hysteresis of spinel/Cr/Fe systems and found novel enhancements of the coercive field of Fe layers. However, it exhibited no oscillation that is observed in IEC in metallic systems e.g. Fe/Cr/Fe.
