Abstract

Abstract: The crystal-electric field parameters are determined for the (Nd0.5 Ho0.5 )2 Fe14 B compound by analyzing experimental magnetization curves obtained in magnetic fields up to 60 T. The values of the crystal-field parameters B 2 0, B 4 0, B 6 0, B 4 4, B 6 4 are 56.3, −73.2, −10.74, −8.9, 0 cm −1 for Nd 3+ ion and 312.38, −176.78, 89.2, −88.43, 0 cm −1 for Ho 3+ ion. The transition from the ferri-to the field-induced ferromagnetic state has been studied in detail.
