Abstract

This paper reports the study of hyperfine field distributions of polycrystalline Fe{sub 54}Ni{sub 26}Cr{sub 20} sample of the substitutionally disordered, isostructural (fcc), ternary alloy by using {sup 57}Fe Moessbauer spectroscopic technique. Magnetic phase transitions occurring in the alloy have been studied by examining the temperature dependence of average hyperfine field. To understand the local magnetic order in this alloy at low temperature, probability of hyperfine field distribution curves have been re-fitted by using three independent Gaussians having different positions and widths. From this fits, local magnetic order of this alloy at low temperature has been described which supports the existence of nonequilibrium ferromagnetic state below Curie temperature. (orig.)
