摘要： There is provided a magnonic-crystal spin wave device capable of controlling a frequency of a spin wave. The magnonic-crystal spin wave device according to the invention includes a spin wave waveguide made of magnetic material, and the spin wave waveguide guides the spin wave so as to propagate in one direction, and includes a magnonic crystal part which has a cross-section orthogonal to the direction, and at least one of a shape, area size, and center line of the cross-section periodically changes in the direction. In accordance with the invention, it is possible to easily control the frequency of the spin wave using the spin wave waveguide made of single magnetic material.
