For metal-free low-dimensional ferromagnetic materials, a hopeful candidate for next-generation spintronic devices, investigating their magnetic mechanisms and exploring effective ways to regulate their magnetic properties are crucial for advancing their applications. Our work systematically investigated the origin of magnetism of a graphitic carbon nitride (Pca21 CN) monolayer based on the analysis on the partial electronic density of states. The magnetic moment of the Pca21 CN originates from the spin-split of the 2 orbit from special carbon (C) atoms and 2 orbit from N atoms around the Fermi energy, which was caused by the lone pair electrons in nitrogen (N) atoms.

- Spin-gapless semiconductors (SGS) are zero-gap materials with fully spin-polarized electrons and holes, making them ideal for efficient spintronics and electronics.
- The Pca21 CN monolayer has been found to have ferromagnetic properties and exhibits SGS-like band structure, with a smaller energy gap in the spin-down channel.
- By adsorbing CO gas on its surface, the band gap of this material can be further optimized, affecting its magnetic properties and enabling transitions between different electronic phases, highlighting its potential for future applications in spintronics.
