Magnetic solids

The band structure of a ferromagnetic solid. The whole chain fans out over the two spin channels, so the input carries a set of Wannier projections for each of them alongside the total magnetization, and you get a band structure per channel at the end.

Ferromagnets only, for the moment: an antiferromagnet needs its two magnetic sublattices started antiparallel, and a structure whose sublattices are inequivalent cannot yet be written in an input file — issue #74 tracks that gap.

Note

This tutorial has not been written yet. It is tracked by issue #76.
