Abstract
Provided are a method of generating strong spin waves, a method of simultaneously generating spin waves and electromagnetic waves, a logic operation device using spin waves, a variety of spin wave devices employing the same, and a method of controlling phases of spin waves. In the method of generating spin waves, strong spin waves are generated by supplying various shapes of energies to a magnetic material in which a magnetic vortex and magnetic antivortex spin structures exist separately or together. In the logic operation device, wave factors of frequency, wavelength, amplitude, and phase of a spin wave generated by the method of generating spin waves are controlled and wave characteristics such as reflection, refraction, transmission, tunneling, superposition, interference, and diffraction are used.
