Fig. 1From: Thermal Behaviour of Sm0.5 R 0.5FeO3 (R = Pr, Nd) Probed by High-Resolution X-ray Synchrotron Powder DiffractionConcentration dependence of the unit-cell dimensions in the SmFeO3–PrFeO3 and SmFeO3–NdFeO3 systems. The orthorhombic lattice parameters are normalized to the perovskite cell as follows: a p = a o /√2, b p = b o /√2, and c p = c o /2Back to article page
