Abstract
The anisotropy compensation and magnetostrictive properties of Tb 1− x Ho x (Fe 0.8Co 0.2) 2 (0.60 ≤ x ≤ 1.0) alloys have been investigated. The easy magnetization direction (EMD) at room temperature rotates from the 〈1 1 1〉 axis ( x ≤ 0.75) to the 〈1 0 0〉 axis ( x ≥ 0.90) through an intermediate state 〈1 1 0〉, subjected to the anisotropy compensation between Tb 3+ and Ho 3+ ions. Composition anisotropy compensation is realized near x = 0.75. The Tb 0.25Ho 0.75(Fe 0.8Co 0.2) 2 alloy has a minimum anisotropy and a large spontaneous magnetostriction coefficient λ 111 (≈740 ppm) at room temperature. The strong 〈1 1 1〉-oriented 1-3 epoxy-bonded composite has been fabricated by curing under a moderate magnetic field. A high low-field magnetostriction of about 400 ppm at 3 kOe is obtained for the 1-3 epoxy/Tb 0.25Ho 0.75(Fe 0.8Co 0.2) 2 composite with 40-vol% alloy particles, which can be attributed to the low magnetic anisotropy, EMD lying along 〈1 1 1〉 direction, the strong 〈1 1 1〉-textured orientation and the chain structure.
