Landau theory and giant room-temperature barocaloric effect in MF${}_3$ metal trifluorides

A. Corrales-Salazar, R. T. Brierley, P. B. Littlewood +1

The structural phase transitions of MF${}_3$ (M=Al, Cr, V, Fe, Ti, Sc) metal trifluorides are studied within a simple Landau theory consisting of tilts of rigid MF${}_6$ octahedra asso…
