TbScGe is obtained as pure phase after melting of the constituents followed by an annealing at 1173K. Contrary to what was suggested previously, this ternary germanide does not present a high temperature form with the hexagonal Ti 5 Ga 4 -type structure after melting and quenching; the as quenched sample is a mixture based on the two solid solutions (Tb 1− x Sc x ) 5 Ge 3 and Tb 1− x Sc x . TbScGe adopts the tetragonal CeScSi-type structure with a=4.219 and c=15.452Å as unit cell parameters. Its investigation by magnetization and specific heat measurements reveals a ferromagnetic behavior below T C =250K inducing a moderate magnetocaloric effect; for a magnetic field change of 2T, the magnetic entropy change ΔS m is equal to −1.6JK −1 kg −1 which corresponds to an adiabatic temperature change ΔT ad of 1.25K.
