Computing with mutually synchronized topological insulator based spin Hall nano-oscillators

Project description

Computing with more efficient and mutually synchronised nanoscopic microwave oscillators

Spin hall nano-oscillators (SHNOs) and spin torque nano-oscillators (STNOs) are promising devices for use in efficient oscillatory computing. In fact, scientists have demonstrated speech recognition using reservoir computing with a network of four magnetic-tunnel-junction STNOs. However, since individual control of its drive current and local magnetic field is required for each STNO, this approach uses more power, lacks speed and isn’t easily scalable to large networks. The EU-funded SPINHALL project aims to tackle these problems and improve the performance and applicability of SHNOs and their networks. To do so, it will employ the latest breakthroughs in topological insulators and low-magnetisation high-anisotropy ferromagnets to improve the SHNO operating frequency, power consumption and mutual synchronisation. This work will help advance large-scale oscillator networks.
