Magnetization distribution in noncollinear magnetic systems with mutually perpendicular crystal axes

摘要

The method of reconstruction of magnetization distribution in the crystal with noncollinear ordering of magnetic moments in the cubic, tetragonal and orthorhombic crystal structures was described. As an example the neutron diffraction data for ScFe4Al8 were used. It has been shown that in this case noncollinear magnetic system can be conveniently described as composed of three collinear systems. From the analysis of the magnetic structure factors the components of the magnetic moment of each atom in the system can be estimated what further allows for the synthesis of "partial" structure factors. The "partial" structure factors were used as the input data for the reconstruction of "partial" magnetization distributions using the Maximum Entropy Method (MEM). Finally, the full vectorial map of the magnetization distribution was obtained as a linear combination of the "partial" distributions.
