The acquisition of a cryogen-free and integrated Physical Property Measurement System (PPMS) at the University of Utah is a significant advancement that bolsters the research activities in quantum science, bioengineering, and manufacturing at various universities and companies across Utah and the surrounding States. The state-of-the-art PPMS tool enables researchers to investigate the behavior of materials at low temperatures without the need for helium to operate and under various external conditions such as magnetic fields, pressure, and sample rotating angles. The utilization of multifunctional characterization tools like the PPMS is crucial for pushing the frontiers of material understanding and designing new materials with controllable properties. The PPMS's ability to provide conclusive insights into electrical, optical, thermal, and magnetic properties with high spatial resolution greatly benefits the research community within the Intermountain West region. The instrument meets the critical needs of research, education, and training by a diverse and large group of faculty within the Colleges of Science, Mines & Earth Sciences, Engineering, and the School of Medicine. The inclusion of several magneto-optic interfaces adds even more value to the PPMS acquisition. The ability to investigate the ferromagnetic responses of quantum materials using a cryo-ferromagnetic resonance spectroscopy probe is a unique capability that currently does not exist in any facility in the State of Utah and its surrounding regions. This specific feature makes the PPMS a unique capability that fosters collaboration with major semiconducting companies in the area. As such, the PPMS serves as a major open-access user facility where students and staff are constantly trained in the areas of microelectronics, semiconductors, and device engineering. More importantly, students and postdocs across many institutions (R1, R2, and primarily undergraduate institutions) strongly overlap with scientists at regional companies and government laboratories, which allow them to seek internships and job opportunities in the region, furthering scientific advancements and innovation in material science.Pushing the frontiers of understanding the physical behavior of materials and designing new materials with controllable properties demands the utilization of multifunctional characterization tools that can provide conclusive electrical, optical, thermal, and magnetic property insights with sufficient spatial resolution. The cryogen-free and integrated PPMS provides a powerful capability to characterize the physical properties of materials at very low temperatures (100 mK-400 K) and as a function of magnetic fields, pressure, and sample rotating angles. The location of the PPMS within the Materials Core Laboratory at the University of Utah boosts the research of regional companies, promote collaborative research, enhances existing lab outreach activities to underrepresented students in STEM fields, and expands educational programs. The PPMS includes several magneto-optic interfaces to investigate the ferromagnetic responses of quantum materials using a cryo-ferromagnetic resonance spectroscopy probe, a unique capability not present in any facility in the State of Utah and its surroundings. There are currently 11 regional companies that make use of PPMS and help to spur the State’s burgeoning technology industry. The University of Utah offers certificates in microscopy, diffraction, and nanotechnology which are enriched by the addition of the PPMS. Finally, the PPMS data acquired by underrepresented undergrads are presented to the public in a Spanish seminar series where various Spanish-speaking professors and students doing cutting-edge science deliver seminars to inform Hispanic families about the importance of a particular scientific topic. Finally, the cryogen-free PPMS allows users to decrease helium consumption in research activities as well as train and expand the microelectronic workforce in coordination with industry and national laboratories within the State and its surroundings.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

犹他大学的无冷冻物理财产测量系统（PPM）的获取是一项重大进步，它在犹他州和周围国家的各个大学和公司的量子科学，生物工程以及制造量子科学，生物工程以及制造中的研究活动。最先进的PPMS工具使研究人员能够在低温下研究材料的行为，而无需氦气操作和在各种外部条件下，例如磁场，压力和样品旋转角度。 PPMS等多功能表征工具的利用对于推动具有控制特性的新材料的前沿和设计新材料至关重要。 PPMS对具有高空间分辨率的电气，光学，热和磁性的结论性见解的能力有益，从而有益于Intermountains West地区内的研究社区。该工具满足了科学，矿山和地球科学，工程和医学院的多样性和大量教师的研究，教育和培训的关键需求。包含多个磁化接口为PPMS采集增加了更多的价值。使用冷冻铁磁共振光谱探针研究量子材料的铁磁响应的能力是一种独特的能力，目前在犹他州及其周围地区的任何设施中都不存在。此特定功能使PPM成为独特的功能，可以促进与该地区主要的半导体公司的合作。因此，PPM是一个主要的开放访问用户设施，在该设施中，学生和员工在微电子，半导体和设备工程领域进行培训。 More importantly, students and postdocs across many institutions (R1, R2, and primary underlying institutions) strongly overlap with scientists at regional companies and government laboratories, which allow them to seek internal ships and job opportunities in the region, further scientific advancements and innovation in material science.Pushing the frontiers of understanding the physical behavior of materials and designing new materials with controlled properties demands the utilization of multifunctional characterization tools that can provide结论性的电气，光学，热和磁性特性见解，具有足够的空间分辨率。无冰冻和集成的PPM具有强大的能力，可以表征非常低温（100 MK-400 K）的材料的物理特性，并且是磁场，压力和样品旋转角度的函数。 PPM在犹他大学材料核心实验室中的位置促进了区域公司的研究，促进合作研究，增强了现有的实验室外展活动，向STEM领域中代表性不足的学生增强了教育计划，并扩大了教育计划。 PPM包括几个磁化界面，可使用冷冻铁磁共振光谱探针研究量子材料的铁磁响应，这是犹他州及其周围环境中任何设施中都不存在的独特功能。目前有11家区域公司使用PPM，并有助于刺激该州的Brgeoning技术行业。犹他大学提供了显微镜，衍射和纳米技术的证书，通过添加PPM可以丰富。最后，由代表性不足的本科生获得的PPMS数据在西班牙语中的一个系列中呈现给公众，其中各种讲西班牙语的教授和从事尖端科学的学生提供了半手，以告知西班牙裔家庭特定科学主题的重要性。最后，无低温PPMS允许用户减少研究活动中的氦气消耗，并训练和扩大与州及其周围环境中的行业和国家实验室协调的微电子劳动力。这一奖项反映了NSF的法定任务，并通过基金会的知识分子优点和广泛的影响来评估NSF的法定任务，并被认为是宝贵的支持。
