Magnetic recording disk with improved antiferromagnetically coupling film

A magnetic recording disk comprises two ferromagnetic films antiferromagnetically coupled to one another and an antiferromagnetically coupling film located between the two ferromagnetic films. The antiferromagnetically coupling film is formed of an alloy of ruthenium and iron and the ferromagnetic f...

Beschreibung
Zusammenfassung:	A magnetic recording disk comprises two ferromagnetic films antiferromagnetically coupled to one another and an antiferromagnetically coupling film located between the two ferromagnetic films. The antiferromagnetically coupling film is formed of an alloy of ruthenium and iron and the ferromagnetic films are formed of an alloy of cobalt. The disk further comprises nonmagnetic spacer film.
