摘要：
An exchange coupling film comprises a ferromagnetic film and an antiferromagnetic film laminated on the ferromagnetic film, wherein at least a portion of the antiferromagnetic film has a face-centered cubic crystal structure and the antiferromagnetic film comprises an IrMn alloy represented by the general formula of Ir x Mn 100-x , wherein x stands for a value by atomic % satisfying the expression, 2 ≦ x ≦ 80.
