PROBLEM TO BE SOLVED: To provide a magnetoresistive effect film using an oxide magnetic layer in order to fix the magnetization direction of the pinned magnetic layer, which has improved reliability as compared with the prior art, and a magnetoresistive effect head using the same. To do. A magnetoresistive film having a laminated structure in which an orientation control layer 2, an oxide magnetic layer 3, a pinned magnetic layer 4, a nonmagnetic intermediate layer 5, and a free magnetic layer 6 are laminated in this order. orientation control layer 2, a metal oxide, wherein the oxide magnetic layer 3, Co x Fe 3-x O y (x = 1.10~1.71, y excluding 0), characterized in that it consists of.
