MCE effect as a function of temperature. a, b, (a) Entropy change −Δ S(T) = S(T, 0) − S(T, H) at 10 kOe on heating after Field Cooling under 70 kOe (open circles) and during cooling (full circles) with no magnetic field. The inset shows the comparison between the entropy change measured from data in Fig. 4(a) (empty red dots) with that obtained using demagnetization (full red dots) and magnetization (full red squares) M(H) curves. (b)Temperature change Δ T(T) under a 10 kOe magnetic field reduction estimated through equation (2). The inset shows the heat capacity measured during heating after a ZFC process.
