Magnetostriction of Pseudobinary Compounds Pr_0.15 Tb_x Dy_0.85-x Fe_2 (x = 0 to 0.85)

摘要

The compound ingots of Pr_0.15 Tb_x Fe_2 (X = 0 to 0.85) were prepared by arc melting in a water Cu boat using arc furnace under a purified Ar atmosphere. Appropriate annealing (850 deg. C, 100 h) can obtain single Laves phase compound. The magnetostriction for these systems will rise obviously when partially substituted Tb or Dy by Pr.
