Abstract
For the field and temperature dependent anisotropic scattering behavio ur of partly aligned moments of superparamagnetic particles the differ ential scattering cross-section for the 2D scattering pattern has been derived. In the calculations interparticle interference effects have been included. The calculations show that only the anisotropic magneti c scattering contribution depends on interparticle interference effect s whereas the isotropic magnetic part is free of them.
