This grant supports the purchase of a Superconducting Quantum Interference Device (SQUID) magnetometer. The instrument satisfies the current need for a versatile magnetometer that will be used by four groups within the Department of Chemical Engineering and Materials Science (CEMS). The instrument will be employed in an array of projects including magnetic characterization of novel magnetic thin films and heterostructures, magnetic semiconductors, molecular solids, and magnetic nanostructures. This research is on structures that incorporate magnetic materials of many types, from organic magnets to conventional semiconductor and ferromagnetic metals, in a variety of configurations (magnetic semiconductor nanoparticles, single crystals and thin film heterostructures). It is this kind of engineering, where magnetic materials are incorporated into novel device structures, which has been so successful in terms of yielding useful magnetic devices such as Giant MagnetoResistance (GMR) multilayers, spin-valves, tunnel junction based Magnetic Random Access Memory (MRAM) and integrated magnetic metal/semiconductor structures. The intention here is to acquire a workhorse instrument that elevates magnetic characterization capabilities to the level of the materials fabrication and characterization expertise at CEMS, while simultaneously strengthening teaching and education in this area. This is essential to the challenging work of developing materials for spin-electronic devices of the future. The broader impact of the proposed work lies primarily in the education and training of students in the interdisciplinary field of magnetic materials, an area in which the basic experimental skills are highly sought-after in many fields. These researchers will be from both Chemical Engineering and Materials Science programs at the undergraduate, graduate and post-graduate levels. In particular, undergraduate students will become actively involved with the research by taking advantage of the UROP (Undergraduate Research Opportunities Program) and REU (Research Experience for Undergraduates) programs.

该赠款支持购买超导量子干扰装置（SQUID）磁力计。该仪器满足了当前对多功能磁力计的需求，该磁力计将在化学工程和材料科学系（CEMS）中使用的四个组使用。该仪器将用于一系列项目中，包括新型磁性薄膜和异质结构，磁性半导体，分子固体和磁性纳米结构的磁性表征。这项研究是关于结构多种类型的磁性材料的结构，从有机磁铁到常规半导体和铁磁金属，以多种构型（磁性半导体纳米颗粒，单晶和薄膜异质结构）中的各种构型。正是这种工程，将磁性材料纳入了新型设备结构中，在产生有用的磁性设备（例如巨型磁倍率（GMR）多​​层，自旋 - 阀，基于隧道连接的磁性随机接入记忆（MRAM）和集成的磁性金属/半管制器结构）方面一直非常成功。这里的目的是购买一种主力仪器，将磁性功能提升到CEMS的材料制造和特征专业知识的水平，同时加强该领域的教学和教育。这对于为未来的自旋电子设备开发材料的挑战性工作至关重要。拟议工作的更广泛的影响主要在于磁性材料跨学科领域的学生的教育和培训，在许多领域，基本的实验技能在许多领域都受到人们的追求。这些研究人员将来自本科，研究生和研究生水平的化学工程和材料科学计划。特别是，本科生将通过利用Urop（本科研究机会计划）和REU（本科生的研究经验）计划来积极参与研究。
