PythMPG

PythMPG is a Magnetic Point Group (MPG) tensor analysis toolkit.

This python package provides tools to enumerate symmetry properties of all 122 magnetic point groups and to count the number of independent components of arbitrary-rank tensors under those symmetries, as classified by their Jahn symbol.

A major feature of the package is its ability to export data in the form of a .csv file that can be used to build a spreadsheet capable of screening for MPGs based on whether they have certain symmetries or support specied tensor properties. A broader community of users can then use standard spreadsheet tools, such as sorting on columns and hiding columns and rows, to achieve similar ends, without the need to access the python codes themselves.
