Abstract

Current-perpendicular-to-plane structural Fe₃Si/FeSi₂/Fe₃Si trilayered junctions were prepared on Si(111) by facing targets direct-current sputtering combined with a mask method. The shape of magnetization curves evidently exhibited that an antiparallel alignment is realized owing to a difference in the coercive force between the top and bottom Fe₃Si layers. In addition, it was demonstrated that the antiparallel alignment in the wide range of applied magnetic field can be realized by forming a crossover structure, which is owing to an enhanced difference in the effective magnetic field between the top and bottom Fe₃Si layers aligned perpendicularly to each other.
