Monocrystal Mn-Zn ferrite and its application in magnetic heads

Abstract

Mn-Zn ferrite monocrystals are prepared according to the Bridgman method [3]. The following physical parameters are tested in directions [110], [111] and [211]: microhardness and microhomogenity; electrical resistance; Curie temperature; Hc, Ms, Mr; Mössbauer spectra of the monocrystal and random oriented ferrite powders. Four types of heads for hard disk devices (HDD) are prepared and tested [1]. © 1991.
