Abstract

A method for analyzing the domain structure in magnetic powder microparticles based on the Mössbauer effect is proposed. This method has been experimentally verified for gadolinium ferrite-garnet (Gd3Fe5O12) powder particles 40 ± 5 μm in diameter in the vicinity of the magnetic compensation point Tcm = 286 K. It is shown that ferrite particles are single-domain near Tcm and pass to the multidomain state while moving away from Tcm.

Keywords:

domain structure single-domain particles ferrites magnetic compensation point Mössbauer effect.
