Abstract

Magnon excitation and detection systems, apparatus, and methods are provided. The systems and apparatus may include magnon exciters and magnon detectors. The systems and apparatus are used in accordance with methods for exciting and detecting magnons.

Claims (4)

1. A system for communicating data via magnetostatic spin waves, comprising:

a magnon exciter generating magnetostatic spin waves in a ferromagnetic material, the magnetostatic spin waves generated by pulsed modulated oscillating magnetic fields; and

a magnon detector receiving the magnetostatic spin waves propagating through the ferromagnetic material, and converting the pulsed modulated oscillating magnetic fields coupled to the magnetostatic spin waves into a radiofrequency signal.

2. The system of claim 1 , where the radiofrequency signal is converted into a digital signal.
