Multidisciplinary extreme magnetometry: State of the art magnetometry for physical, chemical, biological and engineering applications.

利兹大学在磁学、磁学和磁性材料方面有很强的研究活动。这项研究分为物理学院（自旋电子学、生物物理学和生物技术）、化学学院（生物传感、有机磁体和自旋交叉分子）和工程学院（多铁质和纳米材料）。该工作组由18名学者组成，约40名博士生和博士后，每年的研究收入达数百万英镑。这种密集的活动延伸到约克郡（约克，谢菲尔德）和英国北部（诺丁汉，达勒姆，爱丁堡，格拉斯哥）的其他世界级磁性群。本提案旨在通过为新的、最先进的SQUID-VSM磁力计提供资金来加强这一努力。这一工具将巩固目前的研究工作，同时也扩大各小组之间的研究联系。SQUID-VSM将是一个开放存取设施。在利兹大学，它将用于开展纳米级和/或极端磁性的前沿研究，研究方向有四个：1)新型设备。在这里，我们将开发新的设备，可以超越目前的半导体技术，环保电子和成像工具。ii)受挫补偿新型磁性。目的是了解地质，纳米晶体和其他具有技术或环境相关性和复杂性质的新结构的磁性。iii)多功能材料。这些材料显示出的同时特性允许许多技术应用。我们将测量，除其他外，磁热薄膜，多铁质存储器和自旋交叉分子用于电致发光显示器。（四）保健和生物应用。磁性纳米颗粒的新应用包括水过滤、生物成像和癌症治疗，最近还改变了肿瘤标记等技术。这是一个多学科的企业，与科学领域的最大机遇相一致。-解决一些物理学的重大挑战，包括远离平衡和量子技术的物理学。-发展具有高未来和社会经济效益的项目，例如复杂性科学和合成生物学。-在医学工程、物理化学和人类健康等领域开展前沿课题研究。-在基础技术和仪器仪表等具有最高创造力的领域开辟新的道路。-利用我们在潜在颠覆性技术方面的世界级经验，例如自旋电子学。为了能够实现这些目标，我们需要一个高灵敏度和多用途的磁力计。英国没有一所大学拥有SQUID-VSM，其中仅有的两所最先进的磁强计工具位于英格兰南部（英国皇家研究所和钻石光源）。此外，EPSRC设施列表中明显缺乏SQUID磁力计。因此，北方磁学和多学科小组以及早期职业研究人员的进展在一定程度上由于缺乏获得足够设备的机会而受到阻碍。拨款中的仪器将列入EPSRC开放设施的名单，以加强该地区的联系和研究活动。在这一研究背景下，我们还将与仪器制造商合作，开发世界独有的能力，如磁电和磁光测量。该仪器的应用不仅限于内部项目，还扩展到新的合作项目的建立和磁性材料多学科应用的进展。在资助期间，该仪器将是免费的，预算的一小部分将用于从其他英国大学引进和培训早期职业科学家。

There is a very strong research activity on magnetism, magnetoelectronics, and magnetic materials at Leeds. This research is divided between the School of Physics (spintronics, biophysics and biotechnology), the School of Chemistry (biosensing, organic magnets and spin-crossover molecules) and the Faculty of Engineering (multiferroics and nano-materials). The work groups eighteen academics, about forty PhD students and postdocs, and represents several million pounds in research income per year. This intensive activity extends to other world-class magnetism groups in the Yorkshire (York, Sheffield) and northern Britain (Nottingham, Durham, Edinburgh, Glasgow). This proposal aims to strengthen this endeavour by providing funds for a new, state of the art SQUID-VSM magnetometer. This instrument will underpin the current research effort, while also broadening the research links between groups. The SQUID-VSM will be an open access facility. At Leeds, it will be used to carry out cutting edge studies in nanoscale and/or extreme magnetism in four research paths:i) Novel devices. Here, we will develop novel devices that can outperform current semiconductor technologies, eco-friendly electronics and imaging tools.ii) Frustrated, compensated and novel magnetism. The aim is to understand the magnetism of geological, nanocrystaline and other novel structures with technological or environmental relevance and complex properties.iii) Multi-functional materials. These materials show simultaneous properties that allow for many technological applications. We will measure, amongst others, magneto-caloric epilayers, multiferroics for memory storage and spin-crossover molecules for electroluminescent displays.iv) Health and biological applications. Novel applications of magnetic nanoparticles include water filtering, bio-imaging and cancer therapy, recently transforming technologies such as tumor markingThis is a multidisciplinary enterprise aligned with the greatest opportunities in the scientific landscape:.-Tackling some of Physics Grand Challenges, including Physics far from Equilibrium and Quantum Technologies..-Developing projects with high future and socio-economic benefits, e.g. complexity science and synthetic biology..-Performing research in leading topics, with studies on medical engineering, physical chemistry and human health..-Opening new paths in areas with the highest creativity, such as basic technology and instrumentation. .-Taking advantage of our world-class experience in potentially disruptive technologies, such as spintronics.To be able to fulfil these objectives, we need a highly sensitive and versatile magnetometer. There are no Universities in the UK with a SQUID-VSM, and the only two of these state of the art magnetometry tools are in south England (Royal Institute of Britain and Diamond Light Source). Furthermore, there is a glaring lack of SQUID magnetometers in the list of EPSRC facilities. The progress of magnetism and multidisciplinary groups and early career researchers in the north is therefore partly hampered by a lack of access to adequate equipment. The instrument in this grant will be included in the list of EPSRC open facilities, strengthening links and research activity in the region. Within this research context, we will also work in collaboration with the instrument manufacturers to develop world-exclusive capabilities such as magneto-electric and magneto-optic measurements. The applications of the instrument are not limited to in-house projects, but extend to the establishment of new collaborative projects and the progression in multidisciplinary applications of magnetic materials. For the duration of this grant, the instrument will be free of charge, and a small percentage of the budget will be used to bring and train early career scientists from other UK Universities.
