Microminiature magnonic reservoir computer

A model of a magnonic microreservoir based on a feedback loop with a nanometer-thick yttrium-iron-garnet film was developed. A simulation of the microreservoir response to an input electrical signal applied to an electronic attenuator from an arbitrary waveform generator was carried out. The microreservoirs of various designs were characterized with short-term memory and parity check tasks. Methods to increase the test capacities were considered. The maximum capacities of the short-term memory task of 5.02 and the parity check task of 1.29 were demonstrated. It was shown that the characteristics of the proposed magnonic microreservoirs are comparable with the magnonic reservoirs based on $\mu$m-thick yttrium-iron-garnet films.
