Acquisition of a SQUID Magnetometer

9420672李该合同为购买超导量子干涉装置(SQUID)磁力仪(特别是量子设计MPMS-7)提供部分支持。该仪器将极大地加强几个研究小组正在进行的工作，这些研究小组正在探索先进材料和新型固态结构在中低温下的磁响应。这些研究项目集中于对既显示不相关磁矩又显示有序磁矩的先进金属和非金属材料的全面表征，以及小金属团簇中磁有序的发展。预计在许多感兴趣的情况下，样品的总质量将非常小，这使得有必要使用SQUID磁强计无与伦比的高灵敏度。磁力仪的常规使用将分配给五位主要调查人员：M.Lee，他将担任仪器经理，S.J.Poon，B.Shivaram，L.Bloomfield All的物理系，以及R.N.Grimes的化学系。此外，由于UVA上没有类似的设施，预计还会有一些来自物理、化学、材料科学和电气工程的偶然用户使用该仪器。校园里。***

9420672 Lee This award provides partial support for the acquisition of a superconducting quantum interference device (SQUID) magnetometer (specifically a Quantum Design MPMS-7). This inqtrument will greatly enhance the ongoing work of several research groups probing the magnetic response of advanced materials and novel solid-state structures at moderate to low temperatures. These research projects focus on the thorough characterization of advanced metallic and non-metallic materials which display both uncorrelated and ordered magnetic moments, and on the development of magnetic order in small metallic clusters. It is anticipated that in many cases of interest the total mass of the sample will be very small, making necessary the unparalleled high sensitivity of a SQUID magnetometer. %%% Regular use of the magnetometer will be divided among five principal investigators: M. Lee, who will be the instrument manager, S. J. Poon, B. Shivaram, L. Bloomfield all of the Physics Department, and R. N. Grimes of the Chemistry Department. In addition, a number of incidental users of the instrument from physics, chemistry, materials science, and electrical enineering are anticipated, since no comparable facility exists on thc UVa. campus. ***
