| dc.description.abstractEn | TbScGe is obtained as pure phase after melting of the constituents followed by an annealing at 1173 K. Contrary to what was suggested previously, this ternary germanide does not present a high temperature form with the hexagonal Ti5Ga4-type structure after melting and quenching; the as quenched sample is a mixture based on the two solid solutions (Tb1−xScx)5Ge3 and Tb1−xScx. TbScGe adopts the tetragonal CeScSi-type structure with a = 4.219 and c = 15.452 Å as unit cell parameters. Its investigation by magnetization and specific heat measurements reveals a ferromagnetic behavior below TC = 250 K inducing a moderate magnetocaloric effect; for a magnetic field change of 2 T, the magnetic entropy change ΔSm is equal to −1.6 J K−1 kg−1 which corresponds to an adiabatic temperature change ΔTad of 1.25 K. | |
