CoNbFe soft magnetic thin-film backlayers for glass computer disks

Co84Nb12Fe4 films with very low coercivity down to 1 A/m, anisotropy field 1100 A/m, and saturation magnetic induction 1.1 T have been deposited by rf sputtering onto chemically strengthened glass disk substrates as a backlayer for perpendicular recording Winchester disks. Values of coercivity and a...
