| Abstract: |
Amorphous Gd_{5}Si_{1.8}Ge_{1.8}Sn_{0.4} has been obtained with the help of a high-energy ball milling technique. XRD and DSC measurements confirm the amorphous nature of the milled alloy. The separation of FC and ZFC curves below the ferromagnetic transition temperature indicates a spin glass-like state in the amorphous alloy. Thermal hysteresis has been significantly reduced in the high energy ball-milled alloy compared with that of the crystalline one. For the amorphous Gd_{5}Si_{1.8}Ge_{1.8}Sn_{0.4}, magnetic phase transition takes place in a wide temperature span and RC value reaches around 495 J.kg^{-1}. |
