1. An exchange-coupled film comprising a seed layer, an antiferromagnetic layer, and a ferromagnetic layer disposed in that order from the bottom, magnetization of the ferromagnetic layer being directed in a predetermined direction by an exchange coupling magnetic field generated at an interface between the antiferromagnetic layer and the ferromagnetic layer, wherein the seed layer is a metal layer having a thickness that is smaller than or equal to a critical thickness and having a crystalline phase which extends through from an upper surface to a lower surface of the seed layer.
