The crystal-electric field parameters are determined for the (Nd0.5Ho0.5)(2)Fe14B compound by analyzing experimental magnetization curves obtained in magnetic fields up to 60 T. The values of the crystal-field parameters B-0(2),B-0(4),B-0(6),B-4(4),B-4(6),are 56.3,73.2,10.74,8.9, 0 cm(-1) for Nd3+ ion and 312.38,176.78, 89.2,88.43, 0 cm(-1) for Ho3+ ion. The transition from the ferri-to the field-induced ferromagnetic state has been studied in detail.
