Plotting fermi2d noncolinear

Plotting fermi2d noncolinear example. For more information about fermi2d refer to 2D spin-texture

First download the example files with the code below. Then replace data_dir below.

Downloading example

 data_dir = pyprocar.download_example(save_dir='',
                             material='Fe',
                             code='vasp',
                             spin_calc_type='non-colinear',
                             calc_type='fermi')

importing pyprocar and specifying local data_dir

import os
import pyprocar

data_dir = f"{pyprocar.utils.ROOT}{os.sep}data{os.sep}examples{os.sep}Fe{os.sep}vasp{os.sep}non-colinear{os.sep}fermi"

Spin Texture Projection

By setting spin_texture to be true, You can plot the arrows for the spin textures. By default the projected values of the arrows will be s_z. But you can change this by setting arrow_projection to one of the following ‘x’,’y’,’z’,’x^2’,’y^2’,’z^2’

pyprocar.fermi2D(code = 'vasp',
               dirname=data_dir,
               fermi=5.5962,
               spin_texture=True,
               spin_projection='x',
               arrow_size=3,
               arrow_density=10,
               plot_color_bar=True)

Selecting band indices

You can specify specfic bands with the band indices keyword. band_indices will be a list of list that contain band indices. Below I only plot bands 14,15 Also you can specify the colors of the bands as well with band_colors

band_indices = [[6,7]]
band_colors = [['blue','red']]
pyprocar.fermi2D(code = 'vasp',
               mode='plain_bands',
               fermi=5.5962,
               band_indices = band_indices,
               band_colors=band_colors,
               spin_texture=True,
               arrow_size=3,
