    The magnetocaloric effect of Gd(1-x) Tb (x) alloys with x=0.00, 0.10, 0.20, 0.25, 0.30 and 0.40 was studied. The magnetic ordering temperatures were determined from the magnetization measurement. The data obtained from magnetization and specific-heat measurements as well as by the direct measurement are well comparable within their experimental errors. The values of Delta T (ad) are in the proximity of 2.5 K for field change of 1 T and all studied concentrations. The dependence of magnetocaloric effect on the sample shape anisotropy was documented by the magnetization measurement as well as by the direct measurement.
