Abstract

An in situ Raman spectroscopic study was conducted to explore the pressure-induced phase transformation of ferrite MgFe₂O₄ to 51.6 GPa. Results indicate that MgFe₂O₄ transforms to a high pressure polymorphism at a pressure of 27.7 GPa, which was assigned to an orthorhombic structure. Upon release of pressure to ambient conditions, this high pressure polymorphism of MgFe₂O₄ remains stable. The crystallization of high pressure phase of MgFe₂O₄ is dominated by a diffusionless crystallizing mechanism.
