Method of continuous amplification of surface and transverse coupled elastic-spin waves
专利汇可以提供Method of continuous amplification of surface and transverse coupled elastic-spin waves专利检索，专利查询，专利分析的服务。并且A method of continuous amplification of elastic-spin waves with use of a circuit of a slab ferromagnetic crystal on which a semiconductor layer is superposed comprises generating a propagating waves in the slab, and applying a direct voltage to the semiconductor layer to produce a current of drifting electrons in the layer, inducing an elastic wave in the layer through the propagating wave in the slab which produces a piezoelectric field in the layer, modulating the current of drifting electrons with the piezoelectric field, amplifying the elastic wave in the semiconductor layer and in the slab when the drift velocity of the drifting electron reaches a critical velocity, and applying a constant magnetic field to the circuit to produce a spin-acoustic resonance, the elastic wave in the ferromagnetic slab amplifying the spin wave in the slab through spin-elastic coupling.，下面是Method of continuous amplification of surface and transverse coupled elastic-spin waves专利的具体信息内容。
