项目摘要

Electronic and magnetic materials are important to many current and likely future technologies e.g. superconductors for low energy power transmission and new magnets for sensors, information storage and future quantum computers. Exploration of properties at extremes of low (or high) temperature, high magnetic field and high pressure is important to discover new phenomena and to help understand current outstanding electronic and magnetic materials.To do this we propose to construct the Measurements Platform for Materials at Multiple Extremes (MPMME) as a unique facility for measurements of electronic and magnetic properties under multiple extremes of temperature (down to 300 mK or up to 1000 K) and magnetic field (up to 14 T), and also pressure (up to 100 GPa). It will be essential for supporting current and future research on materials varying from heavy fermion superconductors to transition metal oxides to molecular magnets. The proposed MPMME has two parts; 1. A commercial instrument for physical property measurements (heat capacity, magnetic susceptibility, electronic and thermal transport) at extremes of temperature and field. 2. High pressure capabilities for transport and magnetic measurements will be added through auxiliary equipment designed and built in CSEC (the University of Edinburgh's Centre for Science at Extreme Conditions) which has a strong record of instrumentation design for high-pressure research. New pressure cells will provide state-of-the-art pressure capabilities for the MPMME such as non-metallic cells for high frequency AC measurements, and a Megabar diamond-anvil cell for very high pressures.The discovery of new electronic and magnetic materials is a challenge requiring the combined skills of chemists, physicists, and engineers and the applicants have strong backgrounds in these different disciplines that will be combined to achieve our ambitious goal of discovering new materials with notable properties. UK and international collaborations will be strengthened by measurements made with the MPMME facility. It will also augment the training that we can provide to our students and PDRA's, and underpin equipment commercialisation and our outreach activities.

电子和磁性材料对许多当前和未来可能的技术都很重要，例如用于低能量电力传输的超导体和用于传感器、信息存储和未来量子计算机的新磁体。探索极端低温（或高温）下的性能，强磁场和高压对于发现新现象和理解当前优秀的电子和磁性材料具有重要意义，为此，我们建议建立一个独特的测量平台，用于测量多种极端温度下的电子和磁性（低至300 mK或高至1000 K）和磁场（高至14 T），以及压力（高至100 GPa）。它将是必不可少的支持当前和未来的研究材料从重费米子超导体过渡金属氧化物分子磁铁。拟议的MPMME有两个部分; 1.一种商用仪器，用于在极端温度和磁场下测量物理性质（热容、磁化率、电子和热输运）。2.将通过在CSEC（爱丁堡大学极端条件科学中心）设计和建造的辅助设备增加运输和磁性测量的高压能力，该中心在高压研究仪器设计方面有着良好的记录。新的压力单元将为MPMME提供最先进的压力能力，例如用于高频交流测量的非金属单元，以及用于非常高压力的Megabar金刚石压砧单元。新的电子和磁性材料的发现是一项挑战，需要化学家，物理学家，工程师和申请人在这些不同的学科中具有很强的背景，这些学科将结合起来，以实现我们发现具有显着特性的新材料的宏伟目标。英国和国际合作将通过与MPMME设施进行测量来加强。它还将增加我们可以为学生和PDRA提供的培训，并支持设备商业化和我们的推广活动。
