2017 年，我们发现了四元 i-MAX 相（原子层状固体，其中 M 是一种早期过渡金属，A 是 A 族元素，X 是 C），具有 (M12/3M21/3)2AC 化学性质，其中 M1 和 M2 原子是面内有序的。在此，我们报告了一类磁性 i-MAX 相的发现，其中准二维磁性受挫三角晶格双层覆盖 Mo 蜂窝排列和 Al Kagome 晶格。该族的化学成分为 (Mo2/3RE1/3)2AlC，稀土元素 RE 为 Ce、Pr、Nd、Sm、Gd、Tb、Dy、Ho、Er、Tm 和 Lu。对磁性进行了表征，发现其表现出过多的基态，这是由于存在磁晶各向异性的情况下竞争性磁相互作用的相互作用造成的。
In 2017, we discovered quaternary i-MAX phases—atomically layered solids, where M is an early transition metal, A is an A group element, and X is C—with a (M12/3M21/3)2AC chemistry, where the M1 and M2 atoms are in-plane ordered. Herein, we report the discovery of a class of magnetic i-MAX phases in which bilayers of a quasi-2D magnetic frustrated triangular lattice overlay a Mo honeycomb arrangement and an Al Kagome lattice. The chemistry of this family is (Mo2/3RE1/3)2AlC, and the rare-earth, RE, elements are Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, and Lu. The magnetic properties were characterized and found to display a plethora of ground states, resulting from an interplay of competing magnetic interactions in the presence of magnetocrystalline anisotropy.
