A large manifold of nontrivial spin textures, including the stabilization of monopole‐like fields, are generated by using a completely new and versatile approach based on the combination of superconductivity and magnetism. Robust, stable, and easily controllable complex spin structures are encoded, modified, and annihilated in a continuous magnetic thin film by defining a variety of magnetic states in superconducting dots.

Voltage control of magnetism via electric-field-driven ion migration (magneto-ionics) has generated intense interest due to its potential to greatly reduce heat dissipation in a wide range of information technology devices,...

A voltage-controllable N ion accumulation effect at the outer surface of CoN films, enabling ‘post-stimulated’ learning or forgetting under deep sleep (once voltage stimuli are off), is demonstrated, triggering the development of synapse emulation.
