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.***

该奖项来自材料研究仪器项目，支持西北大学收购物理性能测量系统（PPMS）和一些关键选项。该仪器由Quantum Design Corporation（San Diego，加州）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计划，其中大部分是纳米科学导向的，在西北大学（和一些周边机构）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。 该仪器将大大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400 K的温度范围和9 T的磁场下测量静态/动态磁响应、电/热传输特性和比热。一个样品旋转器将允许研究的角度依赖性的运输性能。将启动进一步扩展能力的计划，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（新低温恒温器中有足够的样品空间来定位必要的组件）。 一些计划将立即受益于仪器，包括硫族化物晶体化学，磁性半导体，新型约瑟夫森结（量子位候选者）和纳米晶线。该奖项来自材料研究仪器项目，支持西北大学收购物理性能测量系统（PPMS）和一些关键选项。该仪器由Quantum Design Corporation（San Diego，加州）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领域的各种基于材料的项目，其中大部分以纳米科学为导向。 西北大学的教师普遍认为他们有能力合成各种新材料，PPMS将大大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各种磁场和温度下的磁、热和电特性。 大多数测量都是由与各个学院相关的研究生和本科生进行的，仪器的存在将使学生有机会了解与正在研究的属性相关的基本测量科学。
