Effect of Mechanical Polishing on the Magnetic Properties of Mn-Zn Ferrite Single Crystals

Abstract

The effect of mechanical polishing on the magnetic properties of single crystals of Mn-Zn ferrite was investigated. The following results were obtained.
(1) The effect of mechanical polishing depends on the crystalline axis, and the order of effectiveness is as follows:

(2) The depth of the deformed surface layer (1∼2 μm) increases with increase in polishing-powder size. The magnetic properties are recovered after etching out the deformed layer.
(3) The crystal structure of the deformed surface layer is found by electron beam diffraction to be amorphous or ultra fine-grained.
