Per-site Cartesian magnetic moments, exactly held in Bohr magnetons.

Module Contents

class httk.atomistic.models.moments.cartesian.CartesianSiteMoments(moments, precision=None)

Bases: httk.atomistic.models.moments.backend.SiteMomentsBackend

Per-site Cartesian magnetic moments, exactly held in Bohr magnetons.

kind = 'cartesian'

property cartesian_moments: httk.core.SurdVector

The exact Nx3 Cartesian moments, one row per site.

property precision: fractions.Fraction | None

How precisely the moments were stated, in Bohr magnetons, or None.

Concrete rather than abstract, so a backend with no source of precision inherits None instead of breaking.
