摘要

The structure and magnetic properties of La_(1-x)Tb_xMn_2Si_2 (0 ≤ x ≤ 0.3) were studied by X-ray powder diffraction and DC magnetization measurements. All the compounds crystallize in ThCr_2Si_2-type structure. Substitution of Tb for La led to a linear decrease in the lattice constants and the unit-cell volume. A ferromagnetic phase for x ≤ 0.15, and an antiferromagnetic phase for x = 0.3 have been observed at about room temperature, whereas the compounds with x = 0.2 and 0.25 exhibit a magnetic phase transition from ferromagnetism to antiferromagnetism.
