MICRO- AND NANO-STRUCTURE AND SURFACE STATE OF SrFe12O19 GRAINS

Abstract

The differences in micro-structure and chemical composition between grains and grain boundaries of a magnetic material based on SrFe12O19 have been established by XRD, XPS, Auger spectroscopy, SEM and EDXA. The indicated techniques allowed to reveal the irregularities of granular hexagonal structure of the ferrit
