Mossbauer spectra of oriented thin sections of magnetite single crystal

Abstract

We report Mössbauer spectra of oriented thin sections of natural magnetite to observe crystallographic orientational dependence of sextet of magnetite.  Two natural magnetite single crystals from Brazil and Russia were prepared.  Among separated 6 peaksdue to internal magnetic field, relative intensities of single crystals were deviated from 2 due to crystal anisotropy.  supposing shape magnetic anisotropy of sample, this result can be explained by the <111> easiest magnetization axis.  This is consistent with the general easiest magnetization axis of spinel ferrite.
