摘要

报道了一种新的铀锇铝化合物U3Os4Al11.84(4)。它结晶为gd3ru4al12型的六角形结构，其中磁性u原子形成有利于磁挫折发生的呼吸kagome晶格。因此，在1.8 K以下和13 T磁场下的磁性和比热性能的测量表明，在5.0 K以下形成的远程磁有序（很可能是反铁磁性的）和一些自旋玻璃样特征之间存在共存/竞争。

Frustrated magnetism of a novel breathing kagome U-network aluminide: U3Os4Al11.84(4)

A novel uranium-osmium-aluminide, namely U₃Os₄Al_11.84(4), is reported. It crystallizes in a hexagonal structure of the Gd₃Ru₄Al₁₂-type where the magnetic U-atoms are forming a breathing kagome lattice favorable for the occurrence of magnetic frustrations. Accordingly, measurements of the magnetic and specific heat properties, down to 1.8 K and under magnetic fields up to 13 T, show the coexistence/competition between the formation of a long-range magnetic ordering below 5.0 K – most probably of antiferromagnetic nature - and some spin-glass-like features.
