IMR: Acquisition of a Physical Property Measurement System for Research and Education

这份来自材料研究仪器项目的合同支持西北大学获得物理特性测量系统（PPMS）和一些关键选项。该仪器由加州圣地亚哥量子设计公司制造，该公司是提供所需选项的唯一供应商。该仪器将广泛支持各种基于材料的项目，其中大部分以纳米科学为导向，在西北大学（以及一些周边机构）涉及各种学科，包括化学、材料科学、物理、机械工程和电气工程。该仪器将极大地扩展西北大学教师合成和表征各种新材料的能力。简而言之，该仪器将在0.4K至400K的温度范围和9T的磁场范围内测量静态/动态磁响应，电/热输运性质和比热。一个旋转器样品将允许研究输运性质的角依赖性。将启动进一步扩展功能的计划，包括：静态/动态磁光克尔效应（MOKE）和其他光学测量，声音传播和微波响应（在新的低温恒温器中有足够的样品空间来定位必要的组件）。一些将立即受益于仪器的项目包括硫系晶体化学、磁性半导体、新型约瑟夫森结（量子比特候选者）和纳米晶线。这份来自材料研究仪器项目的合同支持西北大学获得物理特性测量系统（PPMS）和一些关键选项。该仪器由加州圣地亚哥量子设计公司制造，该公司是提供所需选项的唯一供应商。该仪器将广泛支持西北大学和一些周边机构的化学、材料科学、物理、机械工程和电气工程等一系列基于材料的项目，其中大部分以纳米科学为导向。西北大学的教职员工因其合成各种新材料的能力而得到普遍认可，而PPMS将极大地扩展他们表征这些材料的能力。简而言之，该仪器将测量材料在不同磁场和温度下的磁性、热学和电学性能。大多数测量都是由研究生和本科生与各个学院进行的，仪器的存在将使学生有机会了解与所研究的属性相关的潜在测量科学

This award from the Instrumentation for Materials Research program supports Northwestern University with the acquisition of a Physical Properties Measurement System (PPMS) and some key options. This instrument is manufactured by the Quantum Design Corporation of San Diego, California, which is the sole supplier offering the required options. This instrument will broadly support a wide range of materials-based programs, much of it nanoscience oriented, here at Northwestern University (and some surrounding institutions) involving various disciplines including Chemistry, Materials Science, Physics, Mechanical Engineering, and Electrical Engineering. The Instrument will greatly extend the capability at Northwestern University faculty to synthesize and characterize a wide range of new materials. Briefly, the instrument will measure static/dynamic magnetic response, electrical/thermal transport properties, and specific heat, at temperatures in the range 0.4K to 400K and at magnetic fields to 9T. A sample rotator will permit studies of the angular dependence of the transport properties. A program to extend the capabilities still further will be initiated including: the static/dynamic magneto-optical Kerr-effect (MOKE) and other optical measurements, sound propagation, and microwave response (there being sufficient sample space in the new cryostat to locate the necessary components). Some programs which will immediately benefit from the instrumentation include chalcogenide crystal chemistry, magnetic semiconductors, novel Josephson junctions (qubit candidates), and nanocrystalline wires.%%%This award from the Instrumentation for Materials Research program supports Northwestern University with the acquisition of a Physical Properties Measurement System (PPMS) and some key options.

This instrument will broadly support a wide range of materials-based programs, much of it nanoscience oriented, in Chemistry, Materials Science, Physics, Mechanical Engineering, and Electrical Engineering at Northwestern University and some surrounding institutions. Northwestern faculty are generally recognized for their ability to synthesize a wide range of new materials and the PPMS will greatly extend their ability to characterize these materials. Briefly, the instrument will measure magnetic, thermal and electrical properties of materials at various magnetic fields and temperatures. Most measurements are performed by graduate and undergraduate students associated with the various faculty, and the presence of the instrument will give the students the opportunity to learn about the underlying measurement science associated with the properties being studied.***
