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.

本计画的目标是实现奈米磁体与光的超快速且有效的相互作用与控制，以及发展亚ps的近场磁光与光磁学。特别是，该项目旨在实现纳米级磁性的超快（10 ^{-12} s和更快）光学控制和纳米空间分辨率的自旋超快灵敏检测，使用合适的纳米光学结构，如谐振纳米天线和中空纳米锥。该研究计划的目标是启动新技术的开发，以实现前所未有的快速全光记录和磁存储信息的处理。这项研究属于该呼吁的范围，因为它a）通过识别的纳米特定网关（专门设计的纳米光学结构）处理纳米物体（纳米磁体）和更大物体（光）之间的功能耦合，B）提供了实现纳米磁体和光接口的步骤。
