Characterization of the structural, magnetic and Raman properties of 6f – 4d double perovskite compound

The structure and vibrational properties of Pr2FeMnO6 double perovskite are explored in this paper. The compound issynthesized using high temperature solid-state reaction method in airatmosphere. Rietveld analysis of X-ray powder diffraction pattern confirms that the material has orthorhombic structure of space group Pbnm. Room temperature SEM micrograph exhibits the grain size of the particles in the range of 1-5µm. Raman Spectroscopy analysis indicates the strong coupling in two/multi-phonon modes, that are aligned in four strong bands1170, 1356, 1609 and 1838 cm−1. Magnetization study at room temperature reveals the Paramagnetic nature of the material with a saturation magnetization of 18.43 emu/g at the maximum applied field.
