Magneto-optical investigation of the spatial magnetization distribution in a two-layer MIG head

From investigations of the playback spectrum and the local magneto-optical investigation of magnetization on the working surface of a two-layer MIG head, the existence of two additional magnetic gaps at the ferrite/permalloy and permalloy/sendust interfaces has been established. It is concluded that...

Description
Summary:From investigations of the playback spectrum and the local magneto-optical investigation of magnetization on the working surface of a two-layer MIG head, the existence of two additional magnetic gaps at the ferrite/permalloy and permalloy/sendust interfaces has been established. It is concluded that the magnetic field over the former interface is much greater than over the latter.
