摘要：
The spin-1/2 kagome antiferromagnets are key prototype materials for studying frustrated magnetism. Three isostructural kagome antiferromagnets LnCu3(OH)6Cl3(Ln = Gd, Tb, Dy) have been successfully synthesized by the hydrothermal method. LnCu3(OH)6Cl3adopts space group P■m1 and features the layered Cu-kagome lattice with lanthanide Ln3+cations sitting at the center of the hexagons. Although heavy lanthanides(Ln = Gd, Tb, Dy) in LnCu3(OH)6Cl3provide a large effective magnetic moment and ferromagnetic-like spin correlations compared to light-lanthanides(Nd, Sm, Eu)analogues, Cu-kagome holds an antiferromagnetically ordered state at around 17K like YCu3(OH)6Cl3.
