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 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
