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.

利兹大学在磁学、磁电子学和磁性材料方面的研究活动非常活跃。该研究分为物理学院（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（多铁性和纳米材料）。该工作组由 18 名学者、约 40 名博士生和博士后组成，每年带来数百万英镑的研究收入。这种密集的活动扩展到约克郡（约克、谢菲尔德）和英国北部（诺丁汉、达勒姆、爱丁堡、格拉斯哥）的其他世界级磁力集团。该提案旨在通过为新型、最先进的 SQUID-VSM 磁力计提供资金来加强这一努力。该工具将支持当前的研究工作，同时也扩大小组之间的研究联系。 SQUID-VSM 将是一个开放访问设施。在利兹，它将用于在四个研究路径中进行纳米级和/或极端磁性的前沿研究：i）新颖设备。在这里，我们将开发出超越当前半导体技术、环保电子产品和成像工具的新颖设备。ii) 受挫、补偿和新颖的磁性。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特性的新颖结构的磁性。iii) 多功能材料。这些材料同时表现出可用于许多技术应用的特性。除其他外，我们将测量磁热外延层、用于存储器存储的多铁性材料和用于电致发光显示器的自旋交叉分子。iv) 健康和生物应用。磁性纳米粒子的新颖应用包括水过滤、生物成像和癌症治疗，最近正在改变肿瘤标记等技术这是一家多学科企业，与科学领域的最大机遇保持一致：-解决一些物理重大挑战，包括远离平衡的物理和量子技术。-开发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进行领先课题的研究..-在基础技术和仪器等最具创造力的领域开辟新道路。 .-利用我们在潜在颠覆性技术（例如自旋电子学）方面的世界级经验。为了能够实现这些目标，我们需要高度灵敏且多功能的磁力计。英国没有任何大学拥有 SQUID-VSM，并且这些最先进的磁力测量工具中仅有的两个位于英格兰南部（英国皇家研究所和钻石光源）。此外，EPSRC 设施清单中明显缺乏 SQUID 磁力计。因此，北方磁学和多学科团体以及早期职业研究人员的进步在一定程度上因缺乏足够的设备而受到阻碍。这笔赠款中的工具将被纳入 EPSRC 开放设施清单中，以加强该地区的联系和研究活动。在此研究背景下，我们还将与仪器制造商合作开发世界独有的功能，例如磁电和磁光测量。该仪器的应用不仅限于内部项目，还扩展到建立新的合作项目以及磁性材料多学科应用的进展。在这笔资助期间，该仪器将免费，预算的一小部分将用于引进和培训来自其他英国大学的早期职业科学家。
