| Abstract: | The crystal structure and magnetic properties of the intermetallic compounds Tb(Fe_(1-x)Ni_x)_(11.3)Nb_(0.7) were studied by X-Ray Diffraction,SEM and Differential Scanning Calorimetry(DSC) methods,etc.The following consults were obtained:All Tb(Fe_(1-x)Ni_x)_(11.3)Nb_(0.7)(x=0,0.05,0.10,0.15,0.20,0.25) compounds crystallize in ThMn_(12)-type structure.The lattice parameters a,c and the unit-cell volume V all decrease totally with the increase of Ni atom content x.Curie temperature T_c exists a monotonic increasing with Ni atom content x,and the impurity phase was exhibited obviously in the intermetallic compounds Tb(Fe_(1-x)Ni_x)_(11.3)Nb_(0.7) as x>0.15. |
