ERA NanoSci - Femtosecond Nano-Optical Magnetic Recording and Retrieval

本课题的目标是实现纳米磁体与光的超快速、高效的相互作用和控制，发展亚ps近场磁光和光磁。特别是，该项目旨在利用合适的纳米光学结构，如共振纳米天线和空心纳米金字塔，实现纳米尺度超快（10^{-12}s或更快）的磁性光学控制和纳米空间分辨率的超快自旋灵敏检测。该研究计划的一个目标是开发前所未有的快速全光记录和处理磁存储信息的新技术。这项研究是在呼叫的范围内，因为它a)处理纳米物体（纳米磁铁）和更大的物体（光）之间的功能耦合，通过一个确定的纳米特定网关（专门设计的纳米光学结构），b)为纳米磁铁和光的界面提供了可行的步骤。

The goal of this project is to achieve ultrafast and efficient interaction and controlling of nanomagnets with light and to develop sub-ps near-field magneto-optics and opto-magnetism. In particular, the project aims to realize both ultrafast (10^{-12} s and faster) optical control of magnetism at the nanoscale and ultrafast sensitive detection of spins with nanometer spatial resolution, using suitable nano-optical structures such as resonant nano-antennas and hollow nanopyramids. An ambition of the research program is to initiate the development of novel technologies for unprecedented fast all-optical recording and processing of magnetically stored information. The research is in the scope of the call because it a) deals with the functional coupling between a nano-object (nanomagnet) and a larger object (light) through an identified nano-specific gateway (specially designed nano-optical structures) and b) provides enabling steps towards interfacing nanomagnets and light.
