The structure, magnetostriction, and anisotropy compensation of (Tb{sub 1{minus}x}Pr{sub x})(Fe{sub 0.4}Co{sub 0.6}){sub 1.9} (0{le}x{le}1) alloys were investigated. It was found that the matrix of (Tb{sub 1{minus}x}Pr{sub x})(Fe{sub 0.4}Co{sub 0.6}){sub 1.9} alloys is a (Tb,Pr)(Fe,Co){sub 2} phase with a MgCu{sub 2}-type cubic Laves structure, and a second phase of small amount is a (Tb,Pr)(Fe,Co){sub 3} phase when x{le}0.2 and x=0.5 and 1.0. In the range 0.2{lt}x{le}0.4, the amount of the (Tb,Pr)(Fe,Co){sub 3} phase with a PuNi{sub 3}-type structure increases with increasing x and becomes the main phase when x=0.4. When 0.5{lt}x{le}0.6, the (Tb,Pr)(Fe,Co){sub 3} phase increases sharply, whereas the 0.6{lt}x{le}0.8, it decreases with increasing x. The spontaneous magnetostriction {lambda}{sub 111} of the alloys exhibits a peak near x=0.8({lambda}{sub 111}=2370{times}10{sup {minus}6}). The magnetostriction {vert_bar}{lambda}{sub {parallel}}{minus}{lambda}{sub {perpendicular}}{vert_bar} at room temperature was also examined. {copyright} {ital 1997 American Institute of Physics.}
