Fig. 5: Calculated spatial distribution of the charge density for a short Pt atomic wire junction.
From: Magnetic control over the fundamental structure of atomic wires
a, b Isosurfaces of 1.6 Bohr−3 charge density for parallel (a; green) and perpendicular (b; yellow) magnetizations. c, d Isosurfaces of positive (c; red) and negative (d; blue) charge density differences between the parallel and perpendicular magnetizations isosurfaces. The positive and negative components in (c, d) reveal variations in the orbital contribution to the total charge density when changing the magnetization direction.
