| Abstract: | The C15 Laves phases with composition Nd1−xPrx(Fe0.35Co0.55B0.1)2 (0?x?1) have been synthesized by arc melting and subsequent annealing. The Curie temperature Tc and the saturation magnetizations Ms at 5 and 295 K decrease with increasing Pr content. The linear anisotropic magnetostriction λa=λ∥−λ⊥ at room temperature for Nd1−xPrx(Fe0.35Co0.55B0.1)2 alloys with 0?x?0.4 initially reaches a negative minimum, then increases and changes its sign with increasing magnetic field H, and the λa for the alloys with x?0.6 is positive and increases as magnetic field H increases. |
