description: "Perovskite family controls: CaTiO3 (Pnma) and BiFeO3 (R3c) multi-temperature series from COD, showing sign-coherent mild expansion with no colossal axis; BiFeO3 shows the only deviation, a ~3-5 ppm/K excess at its 643 K Neel point."

Perovskite family controls: CaTiO3 (Pnma) and BiFeO3 (R3c) multi-temperature series from COD, showing sign-coherent mild expansion with no colossal axis; BiFeO3 shows the only deviation, a ~3-5 ppm/K excess at its 643 K Neel point.
