项目摘要

Nontechnical Abstract:Magnetic materials have long been recognized for their technological importance, beginning with the compass, and are an integral part of today’s information storage and many other standard applications. However, such applications demand new magnetic materials with new properties. The recently discovered two-dimensional (2D) magnetic materials pose an immense advantage in this regard and offer a unique set of properties that are not possible with the existing magnetic materials. They measure only a few atoms in thickness, they are flexible, and better yet they can be stacked onto each other -much like Lego bricks- to form entirely new materials with new magnetic properties. The goal of this research program is to expand the library of 2D magnets employing a combination of experimental and theoretical methods. The outcome from this project benefits society by offering new magnetic materials for potential applications in data storage, quantum communication, and consumer electronics fields. The proposed multidisciplinary research program also provides an excellent training platform for undergraduate and graduate students, involves K-12 students in active research environment through the Arizona State University SCENE program, and will enable the development of new modules for existing undergraduate and graduate level courses. Technical Abstract: Two-dimensional (2D) van der Waals magnets offer unique opportunities from a fundamental as well as a technological perspective. While the first 2D material graphene was discovered back in 2004, it took more than a decade to show experimental evidence of long-range magnetic order in 2D. To date, magnetic order in 2D has been demonstrated only in a handful of materials and Curie temperatures (Tc) remain lower than 300K which is an important consideration for their disruptive impact in applications. This proposal combines advanced theoretical and experimental techniques to predict, synthesize, characterize, and manipulate the properties of entirely new-classes of 2D magnetic materials: from ferromagnetic insulators, to ferromagnetic half-metals, antiferromagnetic chiral higher order topological insulators and quantum anomalous Hall effect insulators. If successful, these studies will lay a solid foundation to create novel 2D magnets, combine topological order with magnetism in 2D, and take aggressive steps towards demonstrating the first chiral higher order topological insulators while significantly advancing our understanding of magnetism in the 2D to 3D crossover limit, and the effects of pressure, gating, and chemical substitution.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
非技术摘要:磁性材料长期以来一直是其技术的重要性,但从当今的信息的一部分和许多其他标准应用程序开始。磁性材料在此Legard中占据了巨大的优势,并提供G磁性材料。实验和理学方法的结合。 12222 ive研究环境亚利桑那州立大学现场计划,将为现有的本科级课程提供模块:二维(2D)范德华(Van der Waals)从技术角度发现了独特的机会。在2004年,仅在少数材料中证明了2d的订单,而居里温度(TC)仍低于300K,这是它们在应用程序中的破坏性影响的进口。 2D磁性材料:frome tic绝缘子,用于铁磁半米,异常的圣器霍尔神圣绝缘子。绝缘子在2d至3D交叉限制中对磁性的理解以及URE,门控和化学化学替代的影响都显着提高了我们对磁性的理解。该奖项反映了NSF的使命,并通过E基金会的智力优点和更广泛的影响来评估支持,并被认为是支持的。审查标准。
