摘要/描述

Pseudobinary Pr12xTbx(Fe0.6Co0.4)2 (0<x<0.4) cubic Laves single phases have been synthesized by melt spinning and subsequent annealing. Their structure, magnetic properties and stability have been investigated. The composition, at which the anisotropy of Pr12xTbx(Fe0.6Co0.4)2 is compensated, is close to x50.1. The spontaneous magnetostrictions l111 of Pr0.9Tb0.1(Fe0.6Co0.4)2 and Pr0.8Tb0.2(Fe0.6Co0.4)2 are larger than 150031026 and 190031026, respectively. Pr12xTbx(Fe0.6Co0.4)2 (0.1<x<0.4) ribbon-based materials with 3% epoxy resin combine high magnetostriction with significant magnetic coercivity. Pr0.9Tb0.1(Fe0.6Co0.4)2 is a promising magnetostrictive material.
