Abstract

Pressure evolution of LaGaO3, CeGaO3, PrGaO3, NdGaO3, La0.75Pr0.25GaO3 and La0.63Nd0.37GaO3 crystal structures was studied using powder diffraction with synchrotron radiation at ambient temperature in a broad pressure range. Structural instabilities corresponding to phase transformations have been observed in all studied compositions and it was found that P, of these transitions depends on the deformation of the perovskite structure. The effect of the pressure medium on the phase transition, bulk modulus and compressibilities of LaGaO3, CeGaO3, PrGaO3, NdGaO3, La0.75Pr0.25GaO3 and La0.63Nd0.37GaO3 has been discussed in brief.
