报告内容提示:

The electronics industry is quickly approaching the limitation of Moore's Law due to Joule heating in high density-integrated devices. To achieve new higher-speed devices and reduce energy consumption, researchers are turning to spintronics where the intrinsic spin,rather than the charge of electrons, is used to carry information in devices. Advances in spintronics have led to the discovery of giant magnetoresistance (GMR) which is used in hard disk readers and was awarded with the Nobel prize in 2007. Another subject, cavity electrodynamics, promises a completely new quantum algorithm by studying the properties of a single electron interacting with photons inside of a cavity. By merging both spintronics and cavity electrodynamics, a new cutting edge field called Cavity Spintronics is forming, which draws on the advantages of both subjects to develop new devices with higher-speed and less energy consumption.In this work we use innovative spintronics method to study microwave cavity electrodynamics, which reveals interesting features such as the coupling of spin dynamics and Cavity modes, the correlation and evolution of spintronic and photonic damping, etc. We also built a classical model that explains very well our experimental results. This experimental and theoretical work lays a new stone on the foundation of the emerging field of Cavity Spintronics, which paves new ways for controlling spin current in next generation devices utilizing light-matter interaction.
