Title: Investigation of spin reorientation in YMn{sub 1−x}Fe{sub x}O{sub 3} (x = 0.55, 0.6, 0.7, 0.8, 0.9, and 1.0) by Mössbauer spectroscopy

Abstract

YMn{sub 1−x}Fe{sub x}O{sub 3} (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 295 K, analyzed by Rietveld refinement method, showed that all samples were single-phased orthorhombic of Pnma with both Bragg (R{sub B}) and structure (R{sub F}) factors less than 5%. Mössbauer spectra of all samples were obtained at various temperatures ranging from 4.2 to 500 K, and the spectra below T{sub C} 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 Fe{sup 3+}. In addition, temperature-dependent hyperfine field (H{sub hf}), averaged electric quadrupole shift 〈E{sub Q}〉, and averaged isomer shift 〈δ〉 have shown abrupt changes around T{sub SR} due to the change in the charge state of Mn ions.
