| 摘要 |
The present invention provides a magnetoresistive device including a multi-layered structure of a free magnetic layer, a non-magnetic non-conductive layer in contact with the free magnetic layer, a pinned layer in contact with the non-magnetic non-conductive layer, and a pinning layer in contact with the pinned layer for pinning a magnetization direction of the pinned layer, wherein at least any one of the free magnetic layer and the pinned layer has an interface region abutting the non-magnetic non-conductive layer, and at least a part of the interface region includes at least one material selected from the group consisting of CoFeB, CoZrMo, CoZrNb, CoZr, CoZrTa, CoHf, CoTa, CoTaHf, CoFeTi, CoNbHf, CoHfPd, CoTaZrNb, and CoZrMoNi.
