Towards the development of magnetic systems in unconventional computing architectures
Dr. Mehrdad Elyasi, who mainly contributed to this research
Researchers in the field of magnetism and spintronics are actively investigating the physics of magnetic structures to uncover their potential applications in unconventional computing paradigms.
To this end, one area of investigation is the behavior of “magnon parametrons,” where parametrically pumped magnons in magnetic disks exhibit Ising spin-like characteristics1. A 2022 article by Elyasi, Bauer et al. from the AIMR explores the theory of this behavior, emphasizing the importance of thermal and quantum statistics2.
“The controlled stochastic switching observed in the magnon parametron makes it a promising candidate for probabilistic bit operations; furthermore, at low temperatures, quantum effects are predicted to come into play,” says Elyasi. “By understanding the underlying physics of this particular device, the authors are one step closer to the development and implementation of magnetic systems in unconventional computing architectures.”
The team is now finalizing a joint experimental/theoretical article that explores a new strategy to overcome magnetic damping, an important stumbling block for quantum applications of features such as magnon parametrons.
