We report the structural, and magnetic properties as well as magnetocaloric effect of a polycrystalline compound of Tb2Rh3Ge. This compound crystallizes with Mg2Ni3Si-type of rhombohedral Laves phases (space group R3‾m, hR18). The magnetic properties and magnetocaloric effect of Tb2Rh3Ge are explored through dc-magnetization measurements. Temperature dependence of magnetization revealed that the compound exhibits ferromagnetic behavior with TC=56 K. The field dependence of magnetization indicates that Tb2Rh3Ge is a soft ferromagnet. The obtained isothermal magnetic entropy changes (ΔSm) and refrigeration capacity (relative cooling power) for a change of magnetic field 0–9 T are 12.74 J kg−1K−1 and 497(680) J/kg respectively. The Arrott plots and universal curve of normalized ΔSm indicate that this compound undergoes a second order ferromagnetic phase transition.
