英文摘要	We present the structural and magnetic properties of a new compound family, Mg2RE3Sb3O14 (RE = Gd, Dy, Er), with a hitherto unstudied frustrating lattice, the "tripod kagome" structure. Susceptibility (ac, dc) and specific heat exhibit features that are understood within a simple Luttinger-Tisza-type theory. For RE = Gd, we found long-ranged order (LRO) at 1.65 K, which is consistent with a 120 degrees structure, demonstrating the importance of diople interactions for this 2D Heisenberg system. For RE = Dy, LRO at 0.37 K is related to the "kagome spin ice" physics for a 2D system. This result shows that the tripod kagome structure accelerates the transition to LRO predicted for the related pyrochlore systems. For RE = Er, two transitions, at 80 mK and 2.1 K are observed, suggesting the importance of quantum fluctuations for this putative XY system.; U.S. Department of Energy (DOE), Office of Science, Basic Energy Sciences (BES) [FG02-06ER46319]; National Natural Science Foundation of China [11275012]; NSF-DMR [1534741]; NSF [DGE-1339067]; State of Florida; DOE; NHMFL User Collaboration; [NSF-DMR-1157490]; SCI(E); EI; PubMed; ARTICLE; 15; 157201; 116
