摘要：
An example magnetoresistive element includes a first magnetic layer whose magnetization direction is substantially pinned toward one direction; a second magnetic layer whose magnetization direction is changed in response to an external magnetic field; and a spacer layer. At least one of the first magnetic layer and the second magnetic layer includes a magnetic compound layer including a magnetic compound that is expressed by M1aM2bOc (where 5≦a≦68, 10≦b≦73, and 22≦c≦85). M1 is at least one element selected from the group consisting of Co, Fe, and Ni. M2 is at least one element selected from the group consisting of Ti, V, and Cr.
