## Abstract

The ferroelectric phase transition in barium titanate under pressure was studied within the framework of Landau-Ginzburg theory using differential scanning calorimetry. An innovative method for high-sensitive thermal measurements under pressure was demonstrated. It was shown that the relaxation process proceeds nonmonotonically with the formation of intermediate short-lived phases. It was established that polydomain ordering is preferred but the monodomenization of the sample is possible under certain conditions. A narrowing of the temperature hysteresis with increasing pressure was revealed. A new tricritical point in barium titanate crystals characterizing the changing of the phase transition has been experimentally determined and theoretically confirmed.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
