Some physical properties of single crystal manganese ferrites

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

The paper gives the results of measuring the Curie temperatureT c , the Seebeck coefficientθ and the activation energy of electrical conductivityε on single crystal samples of manganese ferrites prepared by two different methods. In the system Mn x Fe3−x O4+y changes in the course of the quantities Tc,θ and ε are observed in the neighbourhood ofx=1 andx=1·9. A qualitative explanation of these courses is given and the influence of oxygen non-stoichiometryγ is discussed.
