The intriguing d0 magnetic properties of partially hydrogenated silicene are investigated via first-principles calculations. H atoms are assembled along the diagonal line of 4×4 supercell. The magnetism can be engineered through transforming the adsorption sites of H atoms. With odd number of H atoms, the systems demonstrate stable magnetism, and the total magnetic moment of each system is 1 μB. No magnetism is found in those systems with equal number of H atoms for sublattice A and sublattice B. Molecular dynamics simulations show the configurations and magnetism of the systems are stable at room temperature. Our work motivates promising applications for silicene in spintronics device.
