  Micromagnetic small-angle neutron scattering theory is well established for
analyzing spin-misalignment scattering data of bulk ferromagnets. Here, this
theory is extended to allow for a global uniaxial magnetic anisotropy (texture)
of the material, in addition to the already included random zero-average local
anisotropy. Macroscopic cross-sections and spin-misalignment response functions
are computed analytically for several practically relevant mutual anisotropy
and external magnetic field orientations in both parallel and perpendicular
scattering geometries for field magnitudes both above and below the rotational
saturation. Some of these expressions are tested on published experimental data
of magnetic-field-annealed Vitroperm and plastically-deformed Ni, allowing to
determine the corresponding global uniaxial anisotropy quality factors.
