Magnetoelectrics: Magnetoelectric Radical Hydrocarbons (adv. Mater. 3/2019)

In article number 1806263, David C. Lacy, Shenqiang Ren, and co-workers achieve ferroelectricity together with magnetic spin exchange coupling in molecular radical hydrocarbon solids through radical–radical interactions, representing a new class of magnetoelectrics. The ability to simultaneously control and retrieve the changes in magnetic and electrical responses opens up a new breadth of applications, such as radical magnetoelectrics, magnets, and optoelectronics.
