The magnetic and magnetocaloric properties of Ni48Co2Mn35In15 were studied using magnetization
and heat capacity measurements. The magnetic entropy change (DSM) was evaluated from both
magnetizing and demagnetizing fields. An inverse DSM for the magnetizing and demagnetizing
processes were found to be 20.5 and 18.5 J kgÀ1
KÀ1
, respectively, for DH ¼ 5 T at the martensitic
