Hoque, M. Hakim, F. Khan, N. Dan] Tb-substituted (Nd,Tb)2Fe14B/Fe3B nanocomposite ribbons have been synthesized by melt spinning of Nd3Tb1Fe76Cu0.5Nb1B18.5 alloys. Tb substitution has significantly enhanced the value of coercivity and Curie temperature. Highest value of coercivity has been obtained as 4.76kOe for the sample annealed at 953K for 10min. Curie temperature of Tb substituted sample, Nd3Tb1Fe76Cu0.5Nb1B18.5 is 549K while Curie temperature of the sample without Tb, Nd4Fe76Cu0.5Nb1B18.5 is 535K. Recoil hysteresis loops measured along the major demagnetization curve are steep having small recoil loop area. Temperature dependence of coercivity, remanent ratio and maximum energy product have been measured for the sample annealed at 893K and 923K for 10min. At 5K, coercivity and maximum energy product of the sample annealed at 893K for 10min are 5.2kOe and 11.5MGOe respectively and the sample annealed at 923K for 10min are 6kOe and 13.1MGOe respectively.
