Abstract
A spin wave device according to an embodiment includes: an input interconnect transmitting an input impulse signal; a multilayer film including a foundation layer; a first magnetic layer formed on the multilayer film and generating spin waves when receiving the input impulse signal, the spin waves propagating through the first magnetic layer; a plurality of input electrodes arranged in a straight line on the first magnetic layer, being connected to the input interconnect, and transmitting the input impulse signal to the first magnetic layer; and a plurality of sensing electrodes sensing the spin waves, being arranged on the first magnetic layer, and being located at different distances from one another from the straight line having the input electrodes arranged therein, and the following equation is satisfied: d=Vg×t0.
