Abstract
Crystallographic and magnetic properties of the double perovskite oxide Ca2FeMoO6 were studied. The single phase polycrystalline Ca2FeMoO6 powder was prepared by a solid-state reaction method. The crystal structure of the Ca2FeMoO6 is found to be monoclinic with lattice constants a0 = 5.4056 Å, b0 = 5.5170 Å, c0 = 7.6971 Å, and β = 89.92°. The Mössbauer spectra have been taken at various temperatures ranging from 17 to Curie temperature (TC) was found to be 350 K. The isomer shift value at room temperature is 0.43 mm/s relative to the Fe metal that are consistent with the Fe3+ valence state. Hyperfine parameters of the Mössbauer spectra were analyzed as a function of temperature and observed the magnetic properties with crystallographic changes through neutron diffraction experiments.
