Abstract Scope |
The family of MXenes as two-dimensional (2D) transition metal carbides, nitrides, or carbonitrides continues to grow with the synthesis of novel phases and their mechanical, optical, and electronic characterizations. However, magnetic characterization of these nanomaterials remains relatively unexplored. MXenes, and the broader 2D material family, have yet to discover a room-temperature ferromagnetic material for commercial use. To expand the understanding of magnetic behavior within MXenes, we first doped MXene precursors Mo2Nb2AlC3 and Mo2TiAlC2 MAX phases with manganese (Mn) to induce a change in magnetic moment. These phases were identified through computational calculations to lie near the energy convex hull, suggesting good metastability. After the Mn-dopped precursor synthesis, wet chemical etching and subsequent delamination were employed to make MXenes for magnetic property measurements. Superconducting quantum interference device magnetometry was employed to provide new insights into tuning magnetism in MXene through elemental doping strategies. |
