摘要：

Zero field cooled and field cooled thermo-magnetizations 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 M-ZFC and M-FC curves and a cusp-like behavior of the former appearing at temperature T-p and T-b, 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.
