Magnetic susceptibility, transport and Mössbauer measurements in CuFeSe<inf>2</inf>

Abstract:

The study of the magnetic, transport and Mössbauer properties of eskebornite, CuFeSe2, shows significant differences from that of its homologous sulfide, chalcopyrite (CuFeS2). From room temperature down to 77 K, CuFeSe2 is paramagnetic and metallic with a non-magnetic Mössbauer spectrum showing two equally populated sites for iron with very small quadrupole splitting. It seems clear that the electronic state of iron has evolved in going from chalcopyrite to eskebornite, in which it has a very weak magnetism. © 1991 J.C. Baltzer A.G. Scientific Publishing Company.
