In this paper, composites with Tb:Dy ratio of 0.30:0.70 and 0.33:0.67 were fabricated by polymer infiltration method. Both maximum d(33) and strain of composites with different Tb/Dy ratio (0.33:0.67, 0.30:0.70) were investigated as a function of the volume fraction of RFe2 phase. The maximum d33 and the strain of composites with higher Tb:Dy ratio (higher magnetocrystalline anisotropy) showed higher than that of composites with lower one as volume fraction of RFe2 increased.
