Abstract

Condensed Matter Materials Science Physics
In 2017, we discovered quaternary i-MAX phases atomically layered solids, where M is an early transitionmetal, A is an A group element, and X is C with a (M1 2/3 M2 1/3)2AC chemistry, where the M1 and M2 atoms are in-planeordered. Herein, we report the discovery of a class of magnetic i-MAX phases in which bilayers of a quasi-2D magneticfrustrated triangular lattice overlay a Mo honeycomb arrangement and an Al Kagomé 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 magneticproperties were characterized and found to display a plethora of ground states, resulting from an interplay of competingmagnetic interactions in the presence of magnetocrystalline anisotropy.
