The perovskite oxide La 1/3 Sr2/3 FeO 3 is a prototypical material in which the superexchange interaction between Fe sites mediated via oxygen ions drives a first-order metal-to-insulator (MIT). By further increasing the bare mass, the transition will turn into a crossover.

The dynamics of the thermally induced first-order structural phase transition in a high-quality single crystal of the organic-inorganic perovskite (C 12 H 25 NH 3) 2 PbI 4 was investigated by optical microscopy. A clear difference of the values for K ∗ and K ∗∗ distinguishes a weak first order transition from a second order one. For example, thermodynamic functions follow the same scaling behavior in a magnetic transition as in the seemingly unrelated gas-liquid transition. Through a detailed study pseudo-critical dynamics in first-order transitions of the mean-field approximation, the Gaussian approximation, the perturbation expansion, and the field-theoretic renormalization-group analysis of a φ 3 theory, we show that the pseudo-critical dynamics in first-order transitions instability fixed points of the theory, together with their associated instability exponents, are quite probably relevant to the scaling and universality behavior exhibited by the first-order.
