llg3d.post.m1_vs_T

Plot the magnetization vs temperature and determine the Curie temperature.

Use the llg3d.m1_vs_T command line tool to plot the average magnetization versus temperature from multiple result files:

$ llg3d.m1_vs_T -h
usage: llg3d.m1_vs_T [-h] [-i IMAGE_FILEPATH] [-s] files [files ...]

Plot the magnetization vs temperature and determine the Curie temperature.

positional arguments:
  files                 Path to the result files.

options:
  -h, --help            show this help message and exit
  -i IMAGE_FILEPATH, --image_filepath IMAGE_FILEPATH
                        Path to save the image (default: m1_vs_T.png)
  -s, --show            Display the plot (omit to disable display in non-
                        interactive runs). (default: False)

When calling the tool on a selection of result files:

$ llg3d.m1_vs_T run_*.npz -i m1_vs_T.png

Functions

main()	Parses the command line to execute processing functions.
plot_m1_vs_T(mag_data[, image_filepath, show])	Plots the data (T, <m_1>).

plot_m1_vs_T(mag_data, image_filepath=None, show=False)

Plots the data (T, <m_1>).

Interpolates the values, calculates the Curie temperature, exports to PNG.

Parameters:

• mag_data (MagTempData) – Magnetization data object

• image_filepath (Path | str | None) – Path to save the image if None, the image will not be saved.

• show (bool) – display the graph in a graphical window

main()

Parses the command line to execute processing functions.
