Magnonic crystal spin devices capable of controlling frequency of spinwaves

摘要

spin wave frequency control is possible mageuno photonic crystal spin wave device is disclosed. The spin wave mageuno photonic crystal frequency control of the spin wave device according to the invention is provided as a spin wave waveguide made of a magnetic material , the spin wave waveguide and the guide so that the spin wave is in progress in one direction , like the direction of the cross section perpendicular to the traveling direction of the spin wave , at least one of the area and the center line includes a photonic crystal mageuno to change periodically. According to the invention , the frequency control of the spin wave is easily possible by using a spin wave waveguide made of a magnetic material of the same type . ; spin wave , mageuno photonic crystal , frequency , waveguide , cycle
