Abstract / Description of output

We report the theoretical and experimental study of evolution of the first-order Raman-active phonons in NdFeO3 with pressure up to 11 GPa at room temperature. With non-polarized light, we have observed 10 Raman-active modes. Our study confirmed no structural phase transition in the studied pressure range. We have calculated that weighted average Grüneisen parameter is ⟨γ⟩  = 1.19.
