Polarized neutron diffraction allows to determine the local susceptibilitytensor on the magnetic site both in single crystals and powders. It is widelyused in the studies of single crystals, but it is still hardly applicable to anumber of highly interesting powder materials, like molecular magnets ornanoscale systems because of the low luminosity of existing instruments and theabsence of an appropriate data analysis software. We show that thesedifficulties can be overcome by using a large area detector in combination withthe two-dimensional Rietveld method and powder samples with magneticallyinduced preferred crystallite orientation. This is demonstrated by revisitingtwo test powder compounds, namely, low anisotropy (soft) ferrimagnetic compoundFe3O4 and spin-ice compound Ho2Ti2O7 with high local anisotropy. The values ofmagnetic moments in Fe3O4 and the susceptibility tensors of Ho2Ti2O7 at varioustemperatures and fields were found in perfect agreement with these foundearlier in single crystal experiments. The magnetically induced preferredcrystallite orientation was used to study the local susceptibility of asingle-molecule magnet Co([(CH3)2N]2CS)2Cl2. Hence, the studies of localmagnetic anisotropy in powder systems might now become accessible.
