中文摘要
磁斯格明子(Skyrmion)是一种具有拓扑保护性质的纳米尺度涡旋磁结构,在下一代超低能耗和超高密度自旋电子器件有巨大的应用前景。为了推进器件的实用化,我们亟需室温下、零磁场和高密度的斯格明子材料。目前大部分研究聚焦于多层磁性金属薄膜,而基于氧化物异质结的磁斯格明子的研究还比较少。不同于金属多层膜,复杂氧化物异质结具有电荷、自旋、轨道和晶格等多种序参量高度关联和耦合,并拥有电荷转移、应力、界面耦合、近邻效应和量子限域等丰富的物性调控手段,为实现高性能斯格明子材料提供了新的机遇。本项目将在前期工作的基础上拟开展氧化物异质结斯格明子材料的制备、调控和器件研究。旨在通过先进的激光分子束外延技术,精准制备高质量的氧化物异质结,发展高性能斯格明子材料,揭示界面调控斯格明子的物理机制,掌握外电场对斯格明子的调控机理,为发展实用型斯格明子材料提供新的思路。
英文摘要
Magnetic Skyrmion which is topologically protected nanoscale swirling spin texture is very promising for next generation ultralow power and ultrahigh density spintronics devices. In order to realize practical application, room temperature, zero-field and high density of Skyrmion is highly desired. In the past decades, intense research has been focused on magnetic metal multilayers with broken inversion symmetry. The newly focused complex transition metal oxide heterostructures provide unprecedented opportunities for realizing high performance of Skyrmion materials. In contrast to metal multilayer, complex transition metal oxides possess multiple degrees of freedoms which delicately couple to each other. What is more, oxide heterostructures offer many knobs to tune the properties by introducing interfacial interaction, charge transfer, strain, proximity effect and quantum confinement. Motivated by anticipated high performance of Skyrmion in oxide heterostructures, this proposal will focus on the creation, manipulation and dynamics of Skyrmion in oxide heterostructures. In order to realize highly stable, small size and controllable magnetic Skyrmion, high quality of oxide heterostructure will be precisely designed and fabricated by laser-MBE. By further revealing the underlying physics and dynamic behavior of Skyrmion under external field, our proposal will pave a new path toward Skyrmion material systems and Skyrmion electronics.
