Topological magnetic skyrmions are particlelike objects that can be created, moved, and annihilated, making them suitable for information storage and logic applications. Toward this goal, most effort is focused on metallic systems, but here the authors use neutron scattering to study electric field control of skyrmion states in a magnetoelectric insulator. Under electric fields, metastable skyrmion states are created, and switching between competing skyrmion and conical topological phases is demonstrated, as well as the antagonistic interplay of thermal agitation and remnant skyrmion states (important for applications near room temperature).
