Abstract

Double rare-earth ferrites Eu0.2R0.8FeO3 (R=rare earth) are synthesized by a high-temperature method. X-ray-diffraction determinations show that all the compounds possess orthorhombic structure. Both 151Eu and 57Fe Mössbauer spectra are measured. The results indicate that the isomer shift of the 151Eu nucleus depends on the unit-cell volume of Eu0.2R0.8FeO3, and the quadrupole interaction of 151Eu Mössbauer spectra is relative to the inverse of the unit-cell volume. The hyperfine field parameter of 57Fe Mössbauer spectra increases linearly with increasing unit-cell volume.
