This application requests funds to purchase a new power supply for the 9-Tesla superconducting magnet of the existing Physical Property Measurement System (PPMS), which failed after many years of operation. The behavior and properties of materials at very low temperatures remain unexplored. The physical property measurement system, PPMS, installed in the applicant's laboratory, permits the study of mechanical, magnetic, electrical and thermal properties and specific heat between 1.8 K and 400 K, in the magnetic field up to 9 Tesla units. The system uses a superconducting magnet that is charged by the magnet's power supply. After many years of operation, the magnet power supply failed, and it cannot be repaired. Without the superconducting magnet, the PPMS system is practically unusable, because most of our studies rely on the measurements of magnetic properties of materials, or the properties that depend on the influence of the magnetic field. The requested new power supply for the PPMS superconducting magnet is central to the research objectives of the applicant. It will bring PPMS to its full operational capabilities. The PPMS represents a critical piece of the equipment needed for the successful continuation of our studies of the properties of Heusler compounds for spintronics and other materials. With fully functional magnetic measurement option, we will investigate the physical properties of materials at the most comprehensive level, and deliver the highest quality results, which are necessary to make a meaningful contribution to our research programs. A fully functional PPMS is critical in the efforts of the applicant to expand the collaboration with other research groups. It permits the education of more students and PDFs, who will gain competence in the hands-on operation of the system and measurement of various materials properties. The HQPs will develop knowledge how the elements of the material microstructure determine the properties, and they will acquire skills in measurements and evaluation of the properties, which are marketable and job-ready. The requested new power supply for the PPMS magnet is instrumental in increasing the scope of our research programs and the number of research collaborations, permitting us to examine new scientific problems in the most exhaustive way and enabling discovery and development of new materials and solutions for innovative technologies, enhancing Canada presence in these areas of science and technology.

该申请要求资金为现有物理性质测量系统（PPMS）的9特斯拉超导磁体购买新的电源，该系统在运行多年后出现故障。材料在极低温度下的行为和性质尚未探索。安装在申请人实验室的物理性能测量系统PPMS允许在高达9特斯拉单位的磁场中研究机械、磁性、电和热性能以及1.8 K至400 K之间的比热。该系统使用超导磁体，由磁体的电源充电。经过多年的运行，磁铁电源出现故障，无法修复。如果没有超导磁体，PPMS系统实际上是无法使用的，因为我们的大多数研究都依赖于对材料磁特性的测量，或者依赖于磁场影响的特性。PPMS超导磁体所需的新电源是申请人研究目标的核心。它将使PPMS充分发挥其业务能力。PPMS代表了我们成功继续研究用于自旋电子学和其他材料的Heusler化合物特性所需的关键设备。通过功能齐全的磁性测量选项，我们将在最全面的水平上研究材料的物理特性，并提供最高质量的结果，这是为我们的研究计划做出有意义的贡献所必需的。一个功能齐全的PPMS是申请人的努力，以扩大与其他研究小组的合作至关重要。它允许更多的学生和PDF的教育，谁将获得动手操作的系统和各种材料性能的测量能力。HQP将发展材料微观结构的元素如何决定性能的知识，他们将获得测量和评估性能的技能，这些性能是可销售的和可工作的。PPMS磁体所需的新电源有助于扩大我们的研究项目范围和研究合作的数量，使我们能够以最详尽的方式研究新的科学问题，并能够发现和开发新材料和创新技术的解决方案，增强加拿大在这些科学和技术领域的存在。
