Abstract
The effect of structural disordering on the magnetic properties and magnetocaloric effect of amorphous (Gd4Co3)1–xGex (x = 0, 0.05, 0.10, 0.15) alloys is studied. The structure of the ribbons after melt-spinning is determined using an x-ray diffractometer. The thermal analysis is performed with the help of a differential scanning calorimeter. The temperature of the start of crystallization is determined. The magnetic properties are measured in a PPMS-9 system. The Curie temperature and the temperature dependence of the magnetization are determined. Different models are used for describing the critical exponents of the magnetic phase transitions.
