Electrochemistry meets magnetism: Toward adaptive memory and computing

Merging electrochemistry with magnetism offers a compelling pathway for next-generation memory and computing technologies by enabling voltage-driven control of magnetic properties through ionic motion and interfacial redox reactions. This approach allows continuous, analog, and history-dependent tuning of magnetism, in contrast to conventional electronic methods based on binary switching, therefore opening opportunities for adaptive functionalities. By dynamically reshaping the material landscape (i.e., modifying magnetic order, anisotropy or exchange interactions) electrochemical modulation supports neuromorphic and in-memory computing architectures where processing and storage are intrinsically coupled. This Editorial highlights recent progress in electrochemically controlled magnetism while addressing key challenges, including time-scale mismatches between ionic and electronic processes, long-term reliability, variability, integration with existing technologies, and the need for standardized performance metrics. More broadly, this emerging computing paradigm points toward a shift from static circuits to dynamic materials that evolve, adapt and compute, embedding intelligence directly within their chemical state and structure.
