ABSTRACT:
An exchange-coupled film has a ferromagnetic layer sandwich comprising a first ferromagnetic layer containing a ferromagnetic material of the body-centered cubic structure and a pair of second ferromagnetic layers containing a ferromagnetic material of the face-centered cubic structure and formed on respective sides of the first ferromagnetic layer; and an antiferromagnetic layer containing a disordered alloy and formed on one of the second ferromagnetic layers. It yields sufficient exchange coupling energy even in smaller thickness of the antiferromagnetic layer than before, whereby it becomes feasible to decrease the thickness of the exchange-coupled film.
