Using the basal functions to form the magnetic moment vectors
The practical usage of
the theory of symmetry for determination of magnetic structure is based on the
following expression S0j=ΣλCνλS(kν/λ|j)
that links the Fourier-components of vector of magnetic moment with the basal
vectors by mix factors. S(kν/λ|j)
is the basal vector, Cνλ is
the mix factor of λ-th basal function. When the basal vectors is complex,
it is impossible to satisfy to condition of complex conjugation of
Fourier-components for the arms k and -k of the two - arms star
in frames of simple variational process. To provide the reality of components
of magnetic moments it is necessary to find some linear combinations of the
basal functions of the arms k and -k. This combination should
satisfy to condition of complex conjugation of Fourier-components for any
values of the mixing factors. The current version of this program doesn't
perform this job. Therefore it is necessary to do this manually. After this
transformation the obtained magnetic structure will satisfy to conditions of
symmetry of the propagation vector.
