The characterisation of ferromagnetic materials in terms of angular dispersion
of the orientation of the macroscopic fields is classically accessed using
magnetisation measurements. However these measurements are not able to
investigate how the resulting magnetic signals are linked to the internal
crystallites and microstructures of the samples since they do not probe crystal
lattices.
Neutron diffraction as the advantage to be able to probe complex magnetic
structures [1], crystallite orientations (texture) from the nuclear
diffraction [2] and magnetic texture from the magnetic diffraction peaks.
It is proposed here to develop a new approach that takes into account all these
scattering contributions, acquiring magnetic diffraction peaks versus sample
orientations, in order to analyse the magnetic orientation distribution
functions (MODF).
