The Tb<sub>60</sub>Ni<sub>30</sub>Al<sub>10</sub> amorphous alloy was prepared by melt-spinning in the form of ribbons. Its magnetic behavior shows upon magnetization the occurrence of a spin glass to ferromagnetic and a paramagnetic to ferromagnetic transitions at 5 and 48 K. The magnetocaloric effects associated with these transitions were investigated. Large positive and negative magnetic entropy changes upon magnetization have been observed in a temperature range interesting for gas liquefaction< Réduire
