The recent discovery of 2D magnetic materials, which are compounds transition metals (TM) with other elements, has opened new avenues for basic research on low-dimensional magnetism and potential applications in spintronics. To further explore magnets pure TM is an interesting topic. Based the first-principles calculations, here a strategy obtaining monolayer magnets, i.e., depositing atoms gra...

Graphynes (GYs) are a series of artificial carbon allotropes composed sp- and sp2-hybridized atoms. Although theoretical studies predict many possible GY structures, synthesizing them as real materials is extremely challenging. Among few synthesized GYs, γ-GY has attracted extensive research interest over the past decade because it predicted to possess fascinating properties such direct bandgap...
