Abstract

ABSTRACT The magnetocaloric effect in RECoIn (RE = Tb, Er) has been studied by means of magnetometric measurements in the function of temperature and applied magnetic field. The maximum magnetic entropy change () at magnetic flux density change () 0–9 T has been determined to be 5.51 J kgK at 47.4 K for TbCoIn and 14.28 J kgK at 12.3 K for ErCoIn, while temperature averaged entropy change (TEC) with 3 K span equals 5.50 and 14.14 J kgK for RE = Tb and Er, respectively. The relative cooling power (RCP) and refrigerant capacity (RC) equal respectively 522.1 and 391.2 J kg in TbCoIn and 605.2 and 463.1 J kg in ErCoIn.
