Summary on Grant Application Form
The study of materials is of fundamental importance to the development of modern day technologies. Advances are only possible because of the efforts of materials physicists and chemists who drive this progress, first discovering new materials and then continually improving the material's properties, and therefore their performance, to enable their use in key industrial applications.

In order to optimize the figure of merit of many materials, it is important to carry out detailed investigations on high quality single crystals of the materials. Without single crystals, it is often not possible to understand the underlying physics of a material. Single crystal growth is therefore of strategic importance, allowing us to work at the forefront of investigations of the physics of condensed matter.

The proposed programme will be carried out within the Superconductivity and Magnetism Group, which is a well-established centre with all the necessary expertise and equipment for both the production of high quality crystals, and the investigation of the properties of, a wide range of new and exotic materials.

In the proposed project, high quality single crystals of oxides, selenides, silicides, borides, and intermetallics will be grown in single crystal form. Target materials include various low-dimensional and frustrated magnets; exotic superconductors; 2D, layered, and magnetic cleavable materials for heterostructures ; topological insulators. The studies of these crystals in the laboratory, complemented by those at central facilities using techniques such as neutron and x-ray scattering, muon spectroscopy, as well as ARPES and measurements in high magnetic fields, will enable a unified picture of the physics of the materials to be developed.

For crystal growth by the floating zone technique, we will use the three different optical mirror furnaces that we have at Warwick (two halogen lamp furnaces and one xenon arc lamp furnace). The optical mirror furnaces allow us to grow crystals under different growth conditions including various gas atmospheres, in pressures of up to 10 bars and at temperatures of up to 3000 degrees C. A proposed upgrade to one of these furnaces will enable it operate at a maximum of 40 bars pressure. Other techniques such as flux growth, Bridgman growth and chemical vapour transport are also available for use for the crystal growth of certain materials, while the Czochralski technique will be used to produce single crystals of intermetallic materials using a tetra-arc furnace.

The crystal growth activity intends to continue to support the existing wide collaborative network that has been built up over many years, and to attract new collaborations. We expect the whole of the UK materials and physics community, as well as many international scientists, to benefit from our work and the provision of high quality single crystal samples.
