The Co substitution caused an increase of magnetization difference Delta M and hence an improvement of the MCE. An inverse giant magnetocaloric effect (IMCE) and a high effective refrigerant capacity RCeff were observed in the x = 3 ribbons. A high amount of Co (x = 5) content led to an inverse magnetic entropy Delta S-M peak with a wide temperature range. Magnetostructural coupling over a wide temperature range is of great importance for technological purposes. On the other hand, the MCE properties were thermal hysteresis dependent, which has to be considered in the technological applications.eninfo:eu-repo/semantics/closedAccessNi– Mn– Sn Heusler alloysRibbonsMagnetocaloric effectThermal hysteresisArticle34258158810.1007/s10948-020-05729-22-s2.0-85093917702Q3WOS:000583904300002Q4
