Investigation of the nuclear and magnetic structures of GaV4S8-ySey materials
Skyrmions, nano-sized topological objects, have recently been found in GaV4S8 and GaV4Se8 materials. In the search of new Skyrmion hosting materials, we have synthesised the GaV4S8-ySey (y = 0 to 8) family of materials. Large changes in the magnetic phase diagrams have been observed via magnetometry in samples with small amounts of substitution to GaV4S8 and GaV4Se8 making these ideal to be studied with neutron diffraction. We have shown samples with small amounts of substitution exhibit a mixed structural phase and propose to study this over the range y=0-0.4 and 7.6-8 using neutron diffraction. We will be using polycrystalline samples (D2B and D20) for our investigations.
