Temperature evolution of the normalized unit cell parameters (a) and linear thermal expansion coefficients (b) of HoCo0.5Cr0.5O3. The orthorhombic lattice parameters are normalized to the perovskite cell as follows: a p = a o/√2, b p = b o/√2, c p = c o/2, V p = V o/4. The values on linear TECs in three crystallographic directions as well volumetric TEC were obtained by differentiation of experimental unit cell dimensions on the temperature. Inset on the right panel shows volumetric TEC of HoCo0.5Cr0.5O3 in comparison with literature data for HoCoO3 [25]
