spin_texture#

FermiSurface.spin_texture(sx, sy, sz, spin=None, interpolation=300)[source]#

This method plots spin texture of the 2d fermi surface

Only 2D layer geometry along z. It is like a enhanced version of ‘plot’ method.

sx, sy, sz are spin projected Nkpoints x Nbands numpy arrays. They also are (already) projected by orbital and atom (from other class)

Parameters:

  • sx (np.ndarray) – Spin projected array for the x component. size (n_kpoints,n_bands)

  • sy (np.ndarray) – Spin projected array for the y component. size (n_kpoints,n_bands)

  • sz (np.ndarray) – Spin projected array for the z component. size (n_kpoints,n_bands)

  • spin (List or array-like, optional) – List of marker colors for the arrows, by default None

  • interpolation (int, optional) – The interpolation level, by default 300

Raises:

RuntimeError – Raise error if find energy was not called before plotting.
