The ratio of longitudinal (R_∥) to transverse (R _⊥) inhomogeneity sizes, where ∥ and ⊥ refer to the applied magnetic field direction, and the product χ₀R _⊥ where χ₀ is the isotropic susceptibility, have been extracted from neutron-depolarization data using two models for the description of anisotropic magnetic inhomogeneities. The analysis of the parameter dependence on temperature and magnetic history leads to conclusions regarding the effects of shape anisotropy. The dynamical excitations are not similar to spin waves.
