Resonator-Like Antenna for Parametric Excitation of Ultra-Short Spin Waves

In novel, beyond Von Neumann, computational approaches the use of magnons (or quanta of spin waves) is particularly promising due to the small intrinsic energies of individual magnons $(\mu \mathrm{V})$, the possibility of using phase, in addition to magnitude, as a state variable, and the possibility to control the magnon dispersion properties in a magnetic sample by varying the direction and magnitude of the bias magnetic field [1].
