Tl: Spin-Orbit unrestricted non-collinear

Sample directory: adf/Tl_noncollinear/

Application of the Spin-Orbit relativistic option (using double-group symmetry, in this case NOSYM) to Tl using the collinear and non-collinear approximation for unrestricted Spin-Orbit calculations

Note: For the collinear and the non-collinear approximation one should use symmetry NOSYM and use the key UNRESTRICTED.

The non-collinear example:

If one replaces the key NONCOLLINEAR with COLLINEAR the collinear approximation will be used instead of the non-collinear approximation. In the case of the collinear approximation default the direction of the magnetization is in the direction of the z-axis. In the non-collinear approximation the magnetization can differ in each point in space.
