The Novel Spin-Based Building Blocks for Advanced TeraHertz Applications (s-NEBULA) project is focused on the research and development of a revolutionary spin-based approach to terahertz (THz) radiation technology for both generation and detection of THz radiation. The ambition of the project is to provide a platform of room-temperature innovative spin-based THz building blocks, arising from novel combinations of magnetism and optics. s-NEBULA will provide cutting-edge solutions to solve bottleneck scientific issues in the THz field motivated by the clear needs in carefully chosen target applications.
