This page is a permanent portal to all work and software related to my work on spin lifetime measurements through Hanle curve fitting.

Generating Hanle fits

This is the recommended procedure for creating your own Hanle fits using evansosenko/spin-lifetime-analysis.

  1. Obtain a copy of the code.
    • Fork or clone the git repository on GitHub.
    • Alternatively, if you are uncomfortable with version control, you can download a compressed archive of the code.
  2. Add you own data under a subfolder in data.
    • Remove any existing data you will not be using, or do not have permission to use.
    • Modify analysis/data.py. This should contain classes that define how to import your data. See scipy_data_fitting.Data.
  3. Define new models or modify existing models in analysis/models.py.
  4. Define new fits or modify existing fits in analysis/fits.py.
  5. Use analysis/analysis.py to control what fits to run and how to save the results.
  6. Follow the instructions in the README on how to run and view the fits.

For details on how to use scipy-data_fitting, refer to the README and core documentation.
