Abstract

The first-principle spin-polarized energy band calculations were performed using the LMTO method in order to determine the total energy and the local moments of the body-centered tetragonal FeRh_1-xPd_x alloys as a function of the axial ratio c a from 0.8 to 1.358. The calculations show that there are competing ferromagnetic and antiferromagnetic states in FeRh alloy with c a=1 and in FeRh_0.5Pd_0.5 alloy with c a=1.238. The first-order magnetic transitions can therefore be induced at finite temperatures as have been observed experimentally in both alloys.
