Ferron-type conductivity in metallic CuFe[Se.sub.2]

It is pointed out that in the compound CuFe[Se.sub.2] the charge transfer in the paramagnetic region is implemented by ferrons of a small radius, as was predicted by N. Mott. At very low temperatures the charge can be transferred by ferrons of a large radius. These results are well confirmed by the...

Description
Summary:It is pointed out that in the compound CuFe[Se.sub.2] the charge transfer in the paramagnetic region is implemented by ferrons of a small radius, as was predicted by N. Mott. At very low temperatures the charge can be transferred by ferrons of a large radius. These results are well confirmed by the temperature dependence of the resistivity and by the metallic type of the conductivity of CuFe[Se.sub.2] and also agree well with the character of charge transfer in magnetic materials.
