Аннотация: We performed an analysis of the phase diagrams and piezocaloric properties of fluorine–oxygen ferroics (NH4)2MeOxF6-x (Me: W, Mo, Nb; x: 1, 2) with orthorhombic symmetry. The nature of the influence of chemical pressure on the caloric efficiency has been elucidated. Substitutions of central atoms, Mo → W and Nb → W, lead to an increase in absolute and integral piezocaloric effects. © 2020 Taylor & Francis Group, LLC.
