Temperature change ∆T vs. applied strain (ε) profiles with different strain rates (a) and calculated COPmaterial values in unloading protocol (b) at 293 K for Ni54Fe19Ga27 single crystal. Strain rates of 0.002, 0.003, 0.008, 0.017 and 0.025 s−1 are selected to perform the loading and unloading processes.
