Abstract

Metallic glasses with ferromagnetism and stable supercooled liquid formed in melt-quenched Gd55Al25TM20 (TM = Cu, Ni, and Co) alloys have been studied by means of vibrating-sample magnetometer (VSM) and differential scanning calorimeter (DSC) These glasses show a large temperature interval between glass transition temperature (Tg) and crystallization temperature (Tx) of about 60K which is comparable with typical metallic glasses. The glasses aer predominantly ferromagnetic with curie temperature (Tc) from 90 K to 120 K and saturation magnetization (σs) between 160 cmu/g and 200 cmu/g.
