- 論文の詳細を見る
Lattice constants and thermomagnetic properties of Cu_<1-ξ>Mg_<ξ>Fe_2O_4 were studied in detail with changing the quenching temperature and with employing a high oxygen pressure furnace. It was confirmed for CuFe_2O_4 that the previously reported inverse-normal change is not due to the simple thermal effect but due to the change in the degree of oxidation, or, due to the generation of Cu^<1+>. This is not the case for MgFe_2O_4 and it was shown experimentally and theoretically that the reasonable representation of the activation energy θ as a function of x, (Mg_xFe_<1-x>) [Mg_<1-x>Fe_<1+x>]O_4, is not θ = θ_0-θ_1x but θ = θ_0+θ_1x-θ_2x^2.
