(spinw-mag-str)=

# spinw.mag_str property

## Sub fields
 
`F`
: Complex magnetization (strictly speaking complex
  spin expectation value) for every spin in the magnetic
  cell, represented by a matrix with dimensions of $[3\times
  n_{magext}\times n_k]$,
  where `nMagExt = nMagAtom*prod(N_ext)` and $n_k$ is the number
  of the magnetic propagation vectors.
 
`k`
: Magnetic propagation vectors stored in a matrix with dimensions
  of $[3\times n_k]$.
 
`N_ext`
: Size of the magnetic supercell in lattice units, default value
  is `[1 1 1]` emaning that the magnetic cell is identical to the
  crystallographic cell. The $[1\times 3]$ vector extends the cell
  along the $a$, $b$ and $c$ axes.
