Description Magnetic and magnetocaloric properties of the intermetallic compound TbAgAl have been investigated. Temperature dependence of magnetization data revealed that TbAgAl exhibits magnetic ordering at 59 K and possesses competing ferromagnetic-antiferromagnetic interactions, which leads to the formation of Griffiths-like phase. The field dependence of magnetization data shows the existence of a metamagnetic-like transition at a critical field of 10 kOe. Unusually potent relaxation effects are seen in the time dependence of magnetization data in the ordered phase. The presence of spin-glass-like state is found to affect magnetocaloric properties of this compound.
