Room-Temperature Multiferroic Liquids: Ferroelectric and Ferromagnetic Order in a Hybrid Nanoparticle-Liquid Crystal System. [PDF]

Adv Mater
A hybrid fluid combining ferrimagnetic nanoplatelets and a ferroelectric nematic displays coexisting magnetization and polarisation at room temperature. This self‐assembled multiferroic shows strong magnetoelectric effect and nonlinear optical response, offering a soft, reconfigurable platform for next‐generation sensing, actuation, and photonic ...
