Abstract (EN): In the present work, we remelt Gd5Si2Ge2 samples previously prepared by arc-melting discharge using a radio frequency heater induction (RF-induction). A detailed analysis of crystal structure was made revealing a mixture of monoclinic (major amount) and orthorhombic (minor amount) phases for both samples. The magnetic measurements show two magnetic phase transitions at T-c similar to 300 K and T-s similar to 282 K for the as-cast samples, corresponding to the magnetic and magnetostructural transition, respectively. For the RF-melted sample only a pure magnetic transition is observed at T-c similar to 300 K showing that in this fabrication process a complete suppression of the magnetostructural transition occurs.
