摘要: The crystal structure, magnetic and magnetocaloric characteristics of the pseduo ternary compounds Tb5Ge2–xSi2–xMn2x (0 ≤ 2x 0.1) were investigated by x-ray powder diffraction magnetization measurements. results show that all preserve monoclinic phase as majority synthesized observed to be ferromagnetic from Magnetic transitions interpreted in terms Landau theory. Maximum isothermal entropy change value (20.84 J kg−1 K−1) was found for Tb5Ge1.95Si1.95Mn0.1 at around 123 K field 5 T.
