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.

该申请要求资金购买现有物理财产测量系统（PPMS）的9台台球超导磁铁的新电源，该电源经过多年的运行后失败了。在非常低的温度下，材料的行为和特性仍未开发。安装在申请人实验室中的物理特性测量系统PPM允许研究机械，磁性，电气和热性能以及在1.8 K和400 K之间的特定热量，最多9 tesla单位。该系统使用磁铁电源充电的超导磁铁。经过多年的运行，磁铁电源失败了，无法修复。没有超导磁铁，PPMS系统实际上是无法使用的，因为我们的大多数研究都取决于材料的磁性特性的测量，或者取决于磁场的影响。 PPMS超导磁铁所需的新电源是申请人研究目标的核心。它将带来PPM的全部运营能力。 PPM代表了成功延续我们对Spimtronics和其他材料的特性研究所需的关键设备。借助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，这对于为我们的研究计划做出有意义的贡献是必要的。功能齐全的PPM对于申请人的努力至关重要，以扩大与其他研究小组的合作。它允许对更多的学生和PDF进行教育，他们将获得系统的动手操作和各种材料属性的测量能力。 HQP将培养知识的材料微观结构的要素如何确定属性，并将获取可销售和准备就绪的物业的测量和评估的技能。 PPMS磁铁的要求的新电源有助于提高我们的研究计划的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，并为创新技术的新材料和解决方案提供了新的材料和解决方案，从而在这些科学和技术领域增强了加拿大的存在。
