Abstract :
The microstructure, magnetic properties and magnetostriction of Tb 0.2Pr0.8(Fe0.4Co0.6)x (1.65⩽×⩽1.90) alloys has been studied. The Curie temperatures for the 1:2 and 1:3 phases decrease with increasing x, whereas the saturation magnetization increases with increasing x. The remanent magnetization remains almost constant for all the samples and the coercivity decreases with increasing x. The spontaneous magnetostriction (λ111) estimated from the splitting of the (440) lines is found to decrease with increasing e. The largest λ111 recorded for Tb0.2Pr0.8(Fe 0.4Co0.61)1.65 is 2900 ppm at room temperature
