Fig. 3From: SnxPy Monolayers: a New Type of Two-Dimensional Materials with High Stability, Carrier Mobility, and Magnetic PropertiesFerromagnetism in P\( \overline{4}{2}_1 \)m-SnP2 monolayer. (a) Spin moments vs hole density nh. b Computed valence band structure of P\( \overline{4}{2}_1 \)m-SnP2 at nh = 7.2 × 1014 cm−2. The spin-up and spin-down bands are shown in blue and red, respectively. The Fermi level is set to be 0 eVBack to article page
