Coexistence of two phases in Sr2TiFeO6 double perovskite

Abstract

In the present study, the structure and magnetic properties of Sr2TiFeO6 have been investigated. This compound is synthesized using standard solid state route and its physical properties are analysed by X-ray diffraction, Raman spectroscopy and room temperature magnetic measurements. Rietveld refinement of X-ray powder diffraction pattern reveals co-existence between cubic and tetragonal phases with Pm3m space group. The scanning electron micrograph exhibits heterogeneous grain distribution with average grain size of 1 µm to 5 µm. Raman spectra of Sr2TiFeO6 reveals six characteristic bands that are in accordance with the group theoretical predictions. Furthermore, the magnetic measurement at room temperature exhibits weak ferromagnetic ordering.In the present study, the structure and magnetic properties of Sr2TiFeO6 have been investigated.
