The phase-separation behavior of the Gd-(Hf,Ti,Y)-Co-Al system has been investigated. The Gd-(Hf,Ti)-Co-Al system undergoes liquid-liquid phase separation during quenching and solidifies into either a Gd-rich phase or a Hf-rich phase (or a TiCo crystalline phase) while the Gd-Y-Co-Al alloy forms a monolithic amorphous state. To investigate the influences of the feature of phase separation and the role of alloying elements on the magnetic properties, the temperature and field dependence of magnetization have also been measured.
