High pressure synthesis and magnetic properties of corundum-type Ga1-xAlxFeO3 (x = 0, 0.25, 0.5)

Schematic of structural transformation of the orthorhombic (Pna21) Ga1-xAlxFeO3(x = 0, 0.25, 0.5) to corundum (R-3c) phase and decomposition of Ga1-xAlxFeO3(x = 1.0) to the constituent binary oxides under high pressure and high temperature.360
