Abstract :
Zero field cooled and field cooled thermomagnetizations of melt-spun and chill-cast amorphous Nd60Fe30Al10 alloys have been investigated with use of regular and nonregular temperature cyclings. The regular temperature treatments revealed the presence of bifurcation of the two MZFC and MFC curves and a cusp-like behavior of the former appearing at temperature Tp and Tb, respectively. These two temperatures show up to scale well with external magnetic field. The magnetization of samples responds sensitively to any sudden change of the temperature and field variation
