The Materials Research Science and Engineering Center (MRSEC) at the University of Nebraska supports an interdisciplinary research program on Quantum and Spin Phenomena in Nanomagnetic Structures (QSPINS). The MRSEC's research is centered on studies of new magnetic materials and structures at the nanometer scale, with the aim of developing fundamental understanding of their properties and related phenomena important for advanced technological applications. QSPINS is organized into two interdisciplinary research groups (IRGs). IRG1 'Nanoscale Magnetism: Structures, Materials and Phenomena' focuses on fundamental physics, chemistry, and materials issues in nanoscale magnets, addressing important quantum, electronic structure, nanofabrication, high-sensitivity measurements, and magnetization-dynamics problems. Nanostructuring has reached a length scale where quantum approaches are needed, and this IRG brings a unique combination of theory, modeling, and new fabrication and measurement methods to the study of novel materials and phenomena. The expected outcomes are new insights into phenomena and structures important for the development of novel cluster-assembled materials, higher energy-density permanent magnets, and information-technology materials. IRG2 'Magnetoelectric Interfaces and Spin Transport' employs the electron spin in a synergistic combination with novel nanoscale magnetic and ferroelectric structures to manipulate spin-dependent properties to yield new scientific concepts and achieve enhanced functionalities. Designed magnetoelectric and piezomagnetic heterostructures are to be investigated where the interplay between electricity, elasticity, and magnetism across interfaces manifests interesting unexplored phenomena, such as electrically-controlled exchange bias and magneto-crystalline anisotropy, and ferroelectrically-tailored spin transport. QSPINS's education and outreach programs encourage gifted young people to pursue scientific careers, broaden the participation of underrepresented groups in science through targeted programs, and improve materials literacy among the general public. As an integral part of the Center, QSPINS offers interdisciplinary training for the next generation of materials scientists and engineers by providing regional four-year institutions experience and tools to improve their materials science programs and curricula, offering opportunities for middle- and high-school teachers and their students to learn about materials science, and by addressing pre-college segments of the educational pipeline via targeted outreach activities. QSPINS maintains shared experimental and computational facilities and supports exploratory Seed Projects to provide continual revitalization of the projects and investigators and promote new interdisciplinary collaborations. QSPINS fosters interactions with industrial companies to leverage the expected scientific innovations for potential technological advances.

内布拉斯加州大学材料研究科学与工程中心（MRSEC）支持纳米磁结构（QSPINS）中的量子和自旋现象的跨学科研究计划。 MRSEC的研究集中在纳米尺度上的新磁性材料和结构的研究上，目的是对其性质和相关现象的基本理解，对先进的技术应用很重要。 Qspins分为两个跨学科研究小组（IRGS）。 IRG1'纳米级磁性：结构，材料和现象'专注于纳米级磁铁中的基本物理，化学和材料问题，解决了重要的量子，电子结构，纳米化，纳米化，高敏度测量以及磁性元素化问题。 纳米结构达到了需要量子方法的长度尺度，这种IRG将理论，建模以及新的制造和测量方法的独特组合带入了新型材料和现象的研究。 预期的结果是对现象的新见解，对于开发新型集群组装材料，更高的能量密度永久磁铁和信息技术材料很重要。 IRG2“磁电界面和自旋传输”采用电子自旋与新型纳米级磁和铁电结构的协同组合，以操纵自旋依赖性特性，从而产生新的科学概念并实现增强的功能。在界面上的电，弹性和磁化之间的相互作用表现出有趣的未探索现象，例如电气控制的交换偏置和磁晶型矛盾型和铁电位封装的旋转旋转旋转旋转。 QSPINS的教育和外展计划鼓励有天赋的年轻人从事科学职业，通过有针对性的计划扩大代表性不足的科学团体的参与，并提高公众的材料素养。 As an integral part of the Center, QSPINS offers interdisciplinary training for the next generation of materials scientists and engineers by providing regional four-year institutions experience and tools to improve their materials science programs and curricula, offering opportunities for middle- and high-school teachers and their students to learn about materials science, and by addressing pre-college segments of the educational pipeline via targeted outreach activities. QSPINS维护共享的实验和计算设施，并支持探索性种子项目，以提供项目和研究人员的持续振兴并促进新的跨学科合作。 Qspins促进了与工业公司的互动，以利用预期的科学创新来实现潜在的技术进步。
