摘要：

We discuss a new class of phenomena that we call "spin plasmonics". It is motivated by three different recent trends of physics research: (i) spintronics, (ii) plasmonics, and (iii) topological properties as is exemplified by the quantized Hall effect. This involves the physics of the "magnetic surface plasmon" (MSP) which provides for an analog of the edge states discussed in the quantized Hall effect. Their properties can be easily tuned by an external magnetic field. They are coupled to the electromagnetic field and can be injected into metallic structures and induce spin and charge currents and hold the promise of miniturization of nonreciprocal devices.
