原始语种摘要: Crystalline structures and magnetic properties of the FeRh1- x Pd x system wereinvestigated. Substitution of Pd for Rh stabilized body-centered tetragonal (bct) structureof the ordered CuAu-type with increasing axial ratio c / a from 1.18 to 1.36. The bctalloys in the range x =0.530∼0.61 exhibited a first-order phase transition fromantiferromagnetic to ferromagnetic state, while the bct alloys with x <0.530 exhibited afirst-order phase transition from antiferromagnetic to Curie paramagnetic state. Both theaxial ratio and the volume increased abruptly at the transitions. A new ferromagnetic phasewith orthorhombic structure with the space group C m m m was found in the bct alloyswith x =0.525∼0.61 below room temperature. This ferromagnetic phase possesses...
