摘要： The magnetostrictive effects of substituting Al for Fe in Pr(AlxFe1-x)1.9 (x=0.0, 0.02, 0.05, 0.10) alloys between 5 K and 300 K were investigated. The substitution decreases the Curie temperature and the value of λ111. Fortunately, the substitution slightly increases the magnetostriction in a low magnetic field, which imbues these materials with potential advantages for applications. Rotation of the easy magnetization direction (EMD) from [111] to [100] in the Pr(Al0.02Fe0.98)1.9 alloy as temperature decreases was detected by step scanned XRD reflections.
