In this work a study of the magnetic behavior in materials based on Gadolinium-Chromium (GdCr) and Iron-Chrome (FeCr), specifically multilayers of GdCr and amorphous tapes based on FeCr. The multilayers were prepared by the Sputtering technique and the tapes by the fast cooling method (Melt spinning). Different aspects of the magnetic behavior of these materials were studied, such as critical exponents, magnetic phase diagrams from magnetization. To experimentally determine magnetization based on temperature and magnetic field, the vibrating sample technique was used by means of a vibrating sample magnetometer (VersaLab by Quantum Design). Additionally, for FeCr-based tapes, we will conduct a study of its magneto-electric characteristics us...
