Fig. 4: Ferrimagnetism of PVD-synthesized 2D p-doped SnSe.
From: Two-dimensional multiferroic material of metallic p-doped SnSe
a, c Temperature-dependent magnetic moment of 2D p-doped SnSe nanosheets with a vertical and parallel magnetic field at 100 Oe. Tmax is defined as the temperature at which the maximum magnetic moment is obtained during the ZFC process. b, d Magnetic hysteresis loops of 2D p-doped SnSe at ~5, ~300, and ~400 K with the magnetic field vertical and parallel to the c-axis, respectively. e Differential charge density of SnSe/SnSe2 (isosurface value of 0.03705 e Bohr–3). Yellow isosurface contours represent the charge accumulation. The same direction of electron indicates the appearance of ferromagnetism. f Projected spin-polarized DOS of SnSe/SnSe2. The Fermi level is set as zero.
