Grain boundary modifications of manganese ferrite

Abstract

dc:description

Complex impedance spectroscopy of Mn ferrite with $\le$1.0 wt% SiO$\sb2$ and CaCO$\sb3$ additions, cooled in air, showed two distinct arcs which were attributed to bulk and grain boundary phenomena. The bulk component was invariant while the grain boundary component varied by less than two orders of magnitude and went through a maximum between 0.2 wt% and 0.4 wt% additions. Only the spinal phase was detected by X-ray diffraction for Mn ferrit with both SiO$\sb2$ and CaCO$\sb3$.
