The magnetocaloric effect (MCE) of Ni45Mn44Sn11 ribbons is simulated, with temperatures ranging from nearly 0 K to 313 K. The MCE of these ribbons exhibits triple peak behavior. Amazingly, three co-occurring peaks of both the inverse and conventional

In this work, a phenomenological model (PM) is used to simulate the magnetocaloric effect (MCE) of GdMn1-xCrxO3 (0 ≤x ≤0.4) (GMCO) samples through the modelling of experimental isofield thermo-magnetization curves. The results showed that the MCE
