Ve. Zubov et al., MAGNETOOPTICAL INVESTIGATION OF THE SPATIAL MAGNETIZATION DISTRIBUTION IN A 2-LAYER MIG HEAD, Journal of magnetism and magnetic materials, 158, 1996, pp. 297-298
From investigations of the playback spectrum and the local magneto-opt
ical investigation of magnetization on the working surface of a two-la
yer MIG head, the existence of two additional magnetic gaps at the fer
rite/permalloy and permalloy/sendust interfaces has been established.
It is concluded that the magnetic field over the former interface is m
uch greater than over the latter.
