Abstract

YMn1- xFexO3 (x=0.55, 0.6, 0.7, 0.8, 0.9, and 1.0) polycrystalline samples were prepared by the solid-state-reaction method. The crystal structure and magnetic properties of samples were investigated with x-ray diffractometer (XRD), vibrating sample magnetometer, and Mössbauer spectroscopy. The XRD patterns at 295K, analyzed by Rietveld refinement method, showed that all samples were single-phased orthorhombic of Pnma with both Bragg (RB) and structure (RF) factors less than 5%. Mössbauer spectra of all samples were obtained at various temperatures ranging from 4.2 to 500K, and the spectra below TC were fitted by least-square method as a function of the Fe and Mn distribution. Isomer shift (δ) values of all samples indicated that the charge states were Fe3+. In addition, temperature-dependent hyperfine field (Hhf), averaged electric quadrupole shift EQ, and averaged isomer shift δ have shown abrupt changes around TSR due to the change in the charge state of Mn ions.
