In this thesis, magnetic structure are introduced through the use of irreducible representation based on crystal symmetries together with their connection to phase transitions. Combined with a presentation of the principles of neutron scattering the foundation is laid for understanding the material properties of the multiferroic Ni3TeO6. This material is a simple representative for the family of function quantum materials useful for future electronic devices due to its ability to switch between two magnetic states by application of an electric field without energy loss. The current literature of Ni3TeO6 is presented together with the new determination of the magnetic phase transition found through multiple neutron scattering experiments. These range from powder diffractometers, over elastic single-crystal experiments to the novel multiplexing instruments.
In the second part, data obtained from measurements of Ni3TeO6 are used to showcase the development undergone in the continuous source triple-axis instruments during the last decades. In particular, the upgrade of the RITA-II instrument at the Paul Scherrer Institute, Switzerland, to utilise the novel CAMEA concept will be presented together with the accompanying challenges of multi-dimensional data, instrument commissioning and normalization, and in particular the development of a full software suite, MJOLNIR. Dealing with the highly complex data conversion and normalization of multi-dimensional neutron scattering data from the instrument CAMEA@PSI cannot be pushed to users. Three different interfaces to the algorithms are presented. A simplified command line scripts, a user-friendly GUI, and a Python scripting library checked by automated testing is presented together with the development philosophy.
