Magnetic Quantitative Texture Analysis Using Isotropic Thermal Neutron Beams

We give the necessary formulas to extract pure magnetic diffraction signals from the difference spectra between two neutron texture measurements, one operated with a sample at zero-magnetic field, and the other under a magnetic field. This enables us to calculate the total-magnetic-scattering ODF, and the polarisation-magnetic-scattering ODF, of an iron sample. Using the developed approach it is shown that under some hypotheses one can describe the three dimensional orientation of the magnetic moments in the sample under a given magnetic field.
