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.

该要求是购买能够在2至800 kelvins的温度范围内提供标准磁性测量值的鱿鱼磁力计。 在材料科学和工程，固态化学和冷凝物理物理学问题的基础研究中，需要使用鱿鱼磁力计。 将使用磁力计的研究包括：对混合金属氧化物中关键的交叉能量和氧化还原能的研究；共价系统中的磁相互作用，例如硫酸盐和pnictides，晶体化学和金属氧化物的性质；永久磁铁合金和固体自由形式制造；粉末和气相激光器加工和纳米粉末加工。 可用的磁力仪将允许培训研究生和本科生的材料合成，表征和加工很重要的技术。 该磁力计将安置在材料科学与工程中心，主要由六名教职员工和其他四名中心使用。 PI和Co-Pi将通过其当前和未决的NSF支持提供维护和操作。 仪器将由PI/Co-Pi（70％使用）与其他三个组共享（30％使用）。 大约有22名学生，7名毕业后和4名本科生将可以使用该乐器。
