Ferron Type of Coductivity in Metal CuFeSe2

TL;DR

This paper investigates ferron-type charge transfer in CuFeSe2, showing that small-radius ferrons dominate at higher temperatures while larger ferrons may occur at very low temperatures, supported by resistivity data.

Contribution

It reveals the presence of ferron-type conductivity in CuFeSe2 and distinguishes between small and large ferrons depending on temperature, expanding understanding of charge transfer mechanisms.

Findings

Ferron-type charge transfer observed in CuFeSe2.

Small-radius ferrons dominate at higher temperatures.

Large-radius ferrons may occur at very low temperatures.

Abstract

It is pointed out, that the charge transfer in the compound in paramagnetic region has a ferron type of transport with ferrons of a small radius, predicted by N. Mott. For some another specimen the charge transfer may be carried out by ferrons of a large radius at very low temperatures. The results are well confirmed by the temperature dependence of resistivity and by metal type of the compound.
