  1. T represents working temperature, \(\left| \sigma \right|\) applied mechanical stress, \(\left| {\Delta S} \right|\) isothermal entropy change, \(\left| {\Delta T} \right|\) adiabatic temperature change, \(\left| {\Delta T} \right|\)/\(\left| \sigma \right|\) mechanocaloric strength, SMA shape-memory alloy, FE ferroelectric, and FIC fast-ion conductor. \(\left| {\Delta T} \right|\) values have been obtained by using zero-pressure specific heat capacities
