Resumo
The purpose of the project is the investigation of the exchange interaction in the following diluted magnetic semiconductors (DMS) : Cd(1-x)Mn(x)X (X = Te, Se, S), Pb(1-x)Ce(x)Se and Sn(1-x)A(x)Te (A = Eu and Gd). In this way, the method that will be used is the magnetization-step (MST) spectroscopy Because magnetic interactions are often weak, it is necessary to carry out the MST measure…
