Magnetic and magnetocaloric properties of TbFeAl and GdFeAl were studied in a wide temperature region in magnetic field up to 10 T. They order magnetically below T-c = 196 K and 259 K for TbFeAl and GdFeAl, respectively.
The temperature change of Delta T = 1.4 K and 1.6 K was observed in GdFeAl and TbFeAl respectively for a field change of 4 T. Interestingly wide temperature region of significant magnetocaloric effect was observed in both compounds which give rise to relative cooling power of 350 J kg(-1) for TbFeAl and 348 J kg(-1) for GdFeAl for 4 T field span.
