Raman signatures of monoclinic distortion in (Ba1-xSrx)(3)CaNb2O9 complex perovskites
Raman signatures of monoclinic distortion in (Ba1-xSrx)(3)CaNb2O9 complex perovskites Abstract: Octahedral tilting is the most common distortion process observed in centrosymmetric perovskite compounds. Indeed, crucial physical properties of this oxide stem from the tilts of BO6 […]
