SUMMARYNearly all of the scientifically important phenomena in condensed matter physics (e.g. complex magnetic behaviour, heavy fermion systems, multiphase superconductors, intermediate valence systems, strongly correlated electron systems, Kondo lattices, quasicrystals, spin fluctuating alloys, quantum phase transitions, etc.) involve alloys or compounds of metals such as the rare earths, refractory transition metals, uranium or thorium. Making high quality research samples of these materials is not trivial, however, and few 'physics' laboratories have the necessary expertise or equipment to carry out fully this vital task themselves. After substantial national investment, the UK condensed matter physics community now has access to some of the world's best neutron, synchrotron and muon facilities; it is imperative, therefore, that it continues to have access to an equally world-class sample preparation service if it is to maintain its international standing. Thus the primary aim of our proposed programme is to use our unique amenities to supply high quality samples, where necessary in single crystal form, for use in a diverse range of studies by any groups in UK universities and research laboratories that have EPSRC support for their research. We plan to augment this programme of sample provision by continuing our research into materials preparation and crystal growth methods, with particular emphasis on the image furnace technique. Here we aim to grow and characterise crystals of Co-doped rutile and orthoferrite materials and to collate a database covering all reported uses of this technique

摘要凝聚态物理学中几乎所有重要的科学现象（例如，复杂的磁行为，重费米子系统，多相超导体，中间价系统，强关联电子系统，近藤晶格，准晶，自旋涨落合金，量子相变等）。涉及金属如稀土、难熔过渡金属、铀或钍的合金或化合物。然而，用这些材料制作高质量的研究样品并不是一件小事，很少有“物理”实验室拥有必要的专业知识或设备来完成这项重要任务。经过大量的国家投资，英国凝聚态物理学界现在可以使用一些世界上最好的中子，同步加速器和μ子设施;因此，如果要保持其国际地位，它必须继续获得同样世界一流的样品制备服务。因此，我们提出的计划的主要目的是利用我们独特的设施提供高质量的样品，必要时以单晶形式，用于英国大学和研究实验室的任何团体的各种研究，这些研究实验室拥有EPSRC支持他们的研究。我们计划通过继续研究材料制备和晶体生长方法，特别是图像炉技术，来增加这一样品提供方案。在这里，我们的目标是生长和结晶钴掺杂的金红石和正铁氧体材料，并整理数据库，涵盖所有报道的使用这种技术
