摘要	Structural, magnetic and magnetostrictive properties of Tb0.2Pr0.8(Fe0.4-xCo0.6+x)(1.93) (0 <= x <= 0.2) alloys have been investigated by means of x-ray diffraction, ac initial susceptibility, a superconducting quantum interference device magnetometer and a standard strain gauge technique. A single (Tb, Pr)(Fe, Co)(2) Laves phase with a cubic MgCu2-type structure is formed when 0.05 <= x <= 0.2. Increasing the Co content in the Tb0.2Pr0.8(Fe0.4-xCo0.6+x)(1.93) alloys reduces the magnetocrystalline anisotropy constant K-1 and improves the magnetostrictive properties at relatively low magnetic fields at room temperature. The Tb0.2Pr0.8(Fe0.35Co0.65)(1.93) alloy with a single Laves phase has a spontaneous magnetostriction lambda(111) as high as 1900 ppm, a large magnetostriction lambda(a) (=lambda(parallel to) - lambda(perpendicular to)) at a relatively low magnetic field and a large lambda(a)/K-1, and may make it a promising magnetostrictive material.
