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

利兹大学在磁学、磁电子学和磁性材料方面有非常强大的研究活动。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、有机磁铁和自旋交叉分子)和工程系(多铁学和纳米材料)。这项工作由18名学者、大约40名博士生和博士后组成，每年代表着数百万英镑的研究收入。这项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)的其他世界级磁性团体。这项提议旨在通过为新的、最先进的SQUID-VSM磁力仪提供资金来加强这一努力。这一工具将支持当前的研究工作，同时也扩大了小组之间的研究联系。Squid-VSM将是一个开放接入设施。在利兹，它将被用来在四个研究途径中进行纳米级和/或极端磁性的尖端研究：i)新设备。在这里，我们将开发能够超越当前半导体技术、环保电子设备和成像工具的新型设备。ii)受挫、补偿和新颖的磁性。其目的是了解地质、纳米晶体和其他与技术或环境相关并具有复杂性质的新型结构的磁性。这些材料同时显示出允许许多技术应用的特性。我们将测量磁热外延层、用于记忆存储的多铁性和用于电致发光显示的自旋交叉分子等。磁性纳米粒子的新应用包括水过滤、生物成像和癌症治疗，最近改变了肿瘤标记等技术。这是一家多学科企业，面临着科学界最大的机遇：-解决一些物理学的重大挑战，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。-在领先主题中进行研究，研究医学工程、物理化学和人类健康。-在基础技术和仪器等最具创造力的领域开辟新的道路。-利用我们在潜在破坏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，我们需要一台高灵敏度和多功能的磁力计。英国没有一所大学拥有SQUID-VSM，其中仅有的两个最先进的磁测量仪器位于英格兰南部(英国皇家研究院和钻石光源)。此外，EPSRC设施清单中明显缺乏SQUID磁强计。因此，北部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受到缺乏适当设备的阻碍。这笔赠款中的工具将被列入EPSRC开放设施清单，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，开发世界独一无二的能力，如磁电和磁光测量。该仪器的应用不仅限于内部项目，还扩展到建立新的合作项目和磁性材料多学科应用的进展。在这笔赠款的有效期内，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.
