内布拉斯加州大学的材料研究科学与工程中心（MRSEC）支持纳米磁性结构（qspin）中的量子和自旋现象的跨学科研究项目。MRSEC的研究集中在纳米尺度上的新型磁性材料和结构的研究，目的是发展对其性质和相关现象的基本理解，这对先进的技术应用很重要。QSPINS被组织成两个跨学科研究小组（irg）。IRG1“纳米级磁性：结构、材料和现象”专注于纳米级磁体的基础物理、化学和材料问题，解决重要的量子、电子结构、纳米制造、高灵敏度测量和磁化动力学问题。纳米结构已经达到了需要量子方法的长度尺度，这个IRG为研究新材料和现象带来了理论、建模和新的制造和测量方法的独特结合。预期的结果是对现象和结构的新见解，对新型簇组装材料、高能量密度永磁体和信息技术材料的发展至关重要。IRG2“磁电界面和自旋输运”将电子自旋与新型纳米级磁性和铁电结构协同结合，以操纵自旋相关特性，从而产生新的科学概念并实现增强的功能。设计的磁电和压磁异质结构将被研究，其中电、弹性和磁性之间的相互作用在界面上表现出有趣的未被探索的现象，如电控制的交换偏压和磁晶各向异性，以及铁电定制的自旋输运。QSPINS的教育和推广项目鼓励有天赋的年轻人追求科学事业，通过有针对性的项目扩大代表性不足的群体对科学的参与，并提高公众的材料素养。作为该中心的一个组成部分，QSPINS为下一代材料科学家和工程师提供跨学科培训，通过提供区域四年制机构的经验和工具来改进他们的材料科学项目和课程，为初中和高中教师及其学生提供学习材料科学的机会，并通过有针对性的外展活动解决大学预科教育管道的部分。QSPINS保持共享实验和计算设施，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。

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.
