Magnetic phase transition from paramagnetic in NbAlC-MAX to superconductivity-like diamagnetic in NbC-MXene: an experimental and computational analysis.

Transition metal carbides (TMCs) have recently emerged as competent members among the family of two-dimensional (2D) materials, owing to their promising applications. There are many promising applications of MXenes; however, their magnetic properties lack a wide margin, both experimentally as well as theoretically, which needs to be investigated for potential use in spintronics. In this study, we carried out a comprehensive etching process selective extraction of Al layers from NbAlC-MAX using a wet electrochemical route under well-optimized conditions to obtain fine 2D-NbC MXene sheets.
