Abstract Quantum anomalous Hall effect (QAHE) is an innovative topological spintronic phenomenon with dissipationless chiral edge states and attracts rapidly increasing attention. However, it has only been observed in few materials in experiments. Here, according to the first-principles calculations, we report that the MXene MoYNCSCl shows a topologically nontrivial band gap of 37.3~meV, possessing QAHE with a Chern number of , which is induced by band inversion between and orbitals. Also, the topological phase transition for the MoYNCSCl can be realized via strain or by turning the magnetization direction. Remarkably, MoYNCSCl shows the nodal-line semimetal state dependent on the electron correlation . Our findings add an experimentally accessible and tunable member to the QAHE family, which stands a chance of enriching the applications in spintronics.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
