Acquisition of SQUID Magnetometer to Augment Magnetics Research

这种基于squid的样品磁力计将在广泛的温度和应用磁场范围内对材料的磁性进行快速，精确的测量。它有一个完整而复杂的计算机操作系统，用于控制和分析，并允许完全自动化。该仪器在灵敏度、温度控制和计算机控制方面都超过了现有设备的能力。该系统将由物理系和化学系的4名教员用于基础材料研究，并将有助于培养本科生和研究生（20人）以及博士后（3人）。SQUID磁力计是几个项目的中心测量和表征仪器：测量通过具有独特成分和结构的新型合成技术制备的超细颗粒的磁性；II-VI混合晶体中光激发载流子的存储和弛豫过程及相关临界现象的研究；稀土金属、过渡金属及其氧化物多层体系的磁各向异性、界面交换及临界现象研究以及有机铁磁体的测量

This SQUID-based sample magnetometer will perform fast, precise measurements of the magnetic properties of materials over a broad range of temperatures and applied magnetic fields. It has a complete and sophisticated computer operating system for control and analysis and allows for total automation. The proposed instrument exceeds current equipment ability in sensitivity, temperature control, and computer control. The system will be used by four faculty members of the Physics and Chemistry departments for fundamental materials research, and will aid in training of undergraduates and graduate students (20), and postdocs (3). The SQUID magnetometer is a central measurement and characterization apparatus for several projects: measurement of magnetic properties of ultrafine parcticles prepared via novel synthetic techniques having unique compositions and structures; studies of storage and relaxation processes of photoexcited charge carriers in II-VI mixed crystals and related critical phenomena; studies of magnetic anisotropy and interface exchange in multilayers of rare-earth metals and transition metals and their oxides and studies of critical phenomena in these systems; and measurements of organic ferromagnets.//
