ABSTRACT
The possibility of the composition anisotropy compensating in Dy[SUB1-x]Pr[SUBx]Fe[SUB2] is discussed phenomenologically, based on a single ion approach. The crystal structure, the easy magnetization direction, and the spontaneous magnetostriction of Tb[SUB0.2]Dy[SUB0.8-x]Pr[SUBx](Fe[SUB0.9]B[SUB0.1])[SUB1.93] (0 ⩽x⩽0.7) alloys are studied. Single-phase Tb[SUB0.2]Dy[SUB0.8-x]Pr[SUBx](Fe[SUB0.9]B[SUB0.1])[SUB1.93] with cubic MgCu[SUB2]-type structure forms up to x = 0.4 and the magnetostrictive phase exists in all the alloys studied. A single (440) peak of x-ray diffraction of the Laves phase exists when 0 ⩽ x ⩽ 0.3, but becomes doubly split when 0.4 ⩽ x ⩽ 0.7 because of a large spontaneous magnetostriction along its easy magnetization direction 〈111〉. Composition anisotropy compensation is realized in (Tb[SUB0.2]Dy[SUB0.8-x]Pr[SUBx](Fe[SUB0.9]B[SUB0.1])[SUB1.93] alloys. Tb[SUB0.2]Dy[SUB0.4]Pr[SUB0.4](Fe[SUB0.9]B[SUB0.1])[SUB1.93] alloy with the single Laves phase has a large magnetostriction (λ[SUB111] &asym; 1200 ppm) and a low anisotoropy, which may be a good candidate material for magnetostriction application.
