Spin waves in magnetic materials are emerging as promising candidates for future low-energy computing technologies due to their minimal dissipation and long coherence length. Antiferromagnets, such as BiFeO₃ (BFO), offer additional advantages, including stability against external fields and enhanced spin transport properties.

In a study of Peter Meisenheimer and co-workers, researchers explored long-range spin transport in an epitaxially engineered, electrically tunable magnonic crystal. They discovered a strong anisotropy in spin-wave propagation, influenced by both population imbalances in dispersion and anisotropic structural scattering. These findings, supported by multiscale theory and simulation, pave the way for reconfigurable magnonic devices controlled via electric fields.

The research was conducted using the Qnami ProteusQ, highlighting its capabilities for advancing next-generation spin-based information processing.
