Investigation of the triple peak magnetocaloric effects of Ni45Mn44Sn11 ribbons

Journal of Materials Research and Technology, 2023
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.
