Concentration dependencies of unit cell dimensions of La1−x Sm x FeO3. Orthorhombic lattice parameters and unit cell volume are normalized to the perovskite ones as follows: a p = a o /√2, b p = b o /√2, c p = c o /2, V p = V o /4. The dashed lines are polynomial fits: a p = 3.9295(9) − 0.115(4) × x + 0.004(4) × x 2 ; b p = 3.935(1) + 0.0119(5) × x + 0.0119(4) × x 2 ; c p = 3.9278(8) −0.067(3) × x − 0.006(3) × x 2 . Arrow indicates the lattice crossover region
