Abstract

The discovery of rare-earth i-MAX phases, denoted by the general formula (RE1/3Mo2/3)2AlC offers a new class of materials that exhibit unique magnetic and structural properties. These materials showcase a unique combination of magnetic frustration and ordering attributed to their distinct, atomically layered, and ordered structure. Moreover, this phase is used as a precursor for the synthesis of two-dimensional materials (MXenes), which offers exciting prospects for the development of new types of conductive, magnetic, or electrochemical materials at the nanoscales. Recently, we have successfully synthesized several rare-earth i-MAX phases using the arc melter technique for the first time and have further synthesized MXenes using these MAX phases. Through comprehensive analyses, including powder X-ray diffraction, specific heat, magnetic susceptibility, neutron diffraction and neutron spectroscopy measurements, we have systematically characterized the structural and physical properties of (Dy1/3Mo2/3)2AlC. This presentation will delve into the synthesis process, structural characterization, and magnetic properties of rare-earth i-MAX phase (Dy1/3Mo2/3)2AlC, highlighting their significance and potential in advancing materials science and technology.
