摘要: The crystal structure, magnetic and magnetostrictive properties of high-pressure synthesized PrxNd1?xFe1.9 (0 ? x 1.0) alloys were studied. exhibit single cubic Laves phase with MgCu2-type structure. initial magnetization curve reveals that Pr0.2Nd0.8Fe1.9 has a minimum magnetocrystalline anisotropy at 5 K. magnetostriction K shows very good low-field property, the alloy in high field is attributable mainly to Pr. temperature dependence (??) kOe substitution Nd reduces K1 remarkably, values ?? Pr0.8Nd0.2Fe1.9 are nearly five times larger than PrFe1.9 below 50 K; reaches up 1082 ppm 100 K, which makes it potential candidate for application this range.
