摘要：
Ternary compounds REMnSb(2) (RE=La, Ce, Pr, Nd, Sm), REZnSb(2) (RE=La, Ce, Pr, Nd, Sm, Gd) and RE=dSb(2) (RE = La, Ce, Pr, Nd, Sm) were synthesized. From room temperature X-ray powder diffractometry all compounds were found to crystallize with the ZrCuSi2-type structure. The magnetic behavior of REMnSb, compounds is characterized by the onset of ferromagnetism of the Mn sublattice in the temperature range between 100 and 520 K. Ordering of the rare-earth sublattice below 50 K is indicated for samples containing Ce, Pr and Nd. CeZnSb2 remains paramagnetic in the temperature range investigated (4.2-550 K).
