This request is for the purchase of a SQUID magnetometer capable of providing standard magnetic measurements over a wide range of temperature, from 2 to 800 Kelvins. The SQUID magnetometer is needed in fundamental studies of problems in materials science and engineering, solid state chemistry, and condensed matter physics. Studies which will make use of the magnetometer include: investigations of the critical cross-over energies and redox energies in mixed-metal oxides; magnetic interaction in covalent systems such as chalcogenides and pnictides, crystal chemistry and properties of metal oxides; permanent magnet alloys, and solid freeform fabrication; powder and gas-phase laser processing and nanometer powder processing. An available magnetometer will allow the training of graduate and undergraduate students in a technique important for materials synthesis, characterization, and processing. This magnetometer will be housed in the Center for Materials Science and Engineering, used primarily by six faculty members and four other members of the center. Maintenance and operation will be provided by the PI and CO-PI through their current and pending NSF support. The instrument willl be shared by the PI/CO-PI (70% use) with three other groups (30% use). About 22 grad students, 7 post-docs, and 4 undergraduate students will have access to this instrument.

此请求旨在购买 SQUID 磁力计，该磁力计能够在 2 至 800 开尔文的宽温度范围内提供标准磁测量。 材料科学与工程、固态化学和凝聚态物理问题的基础研究需要 SQUID 磁力计。 利用磁力计的研究包括：混合金属氧化物中临界交叉能和氧化还原能的研究；共价体系（如硫族化物和磷族化物）中的磁相互作用、金属氧化物的晶体化学和性质；永磁合金和固体自由形状制造；粉末和气相激光加工以及纳米粉末加工。 可用的磁力计将允许对研究生和本科生进行材料合成、表征和加工重要技术的培训。 该磁力计将安装在材料科学与工程中心，主要由该中心的六名教职人员和其他四名成员使用。 维护和操作将由 PI 和 CO-PI 通过其当前和待定的 NSF 支持提供。 该工具将由 PI/CO-PI（使用 70%）与其他三个小组（使用 30%）共享。 大约 22 名研究生、7 名博士后和 4 名本科生将有机会使用该工具。
