摘要	The possibility of the composition anisotropy compensating in Dy1-xPrxFe2 is discussed phenomenologically, based on a single ion approach. The crystal structure, the easy magnetization direction, and the spontaneous magnetostriction of Tb0.2Dy0.8-xPrx(Fe0.9B0.1)(1.93) (0less than or equal toxless than or equal to0.7) alloys are studied. Single-phase Tb0.2Dy0.8-xPrx(Fe0.9B0.1)(1.93) with cubic MgCu2-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 0less than or equal toxless than or equal to0.3, but becomes doubly split when 0.4less than or equal toxless than or equal to0.7 because of a large spontaneous magnetostriction along its easy magnetization direction <111>. Composition anisotropy compensation is realized in Tb0.2Dy0.8-xPrx(Fe0.9B0.1)(1.93) alloys. Tb0.2Dy0.4Pr0.4(Fe0.9B0.1)(1.93) alloy with the single Laves phase has a large magnetostriction (lambda(111)approximate to1200 ppm) and a low anisotropy, which may be a good candidate material for magnetostriction application.
