Abstract

The magnetic behavior of (CuGa)_1-xFe_xSe_2-x solid solutions with compositions x=0.1, 1/3 and 1/2 has been investigated using SQUID techniques. DC magnetic susceptibility was measured in the temperature range 2 < T < 300K using Zero Field Cooling (ZFC) - Field Cooling (FC) protocol. It has been observed that the experimental curves can be analyzed as the sum of two magnetic components, one superparamagnetic and the other one ferromagnetic. The ferromagnetic component persist up to temperatures higher than room temperature making this report the first observation of room temperature ferromagnetism in A^IB^IIIC^VI2 compounds doped (or alloyed) with transition metals.
