Abstract
The departure of the orthorhombic unit cell of perovskite (CaTiO3) from the cubic symmetry can be characterised by the angle of shear, ∅ of the pseudo-cubic sub-cell. We have determined ∅ for a series of strontium-substituted perovskites, of general formula Cai-xSrxTiO3, at room temperature. ∅ decreases linearly with increases in x and extrapolates to zero at x ≈ 0.4, in fair agreement with previous work. For x > 0.4 the structure is cubic, contrary to previous reports.
