A simple and general approach for manipulating magnetic field at room temperature by means of electric fields is reported. Our design involves the fabrication of liquid crystal devices compounded with built-in ferromagnetic nanorods. It is discovered that magnetic nanorods can be well aligned along the orientation of liquid crystal molecules. Electrically assisted magnetic anisotropy rotation has been demonstrated through the effect of the electrical manipulation of magnetic nanorods. In view of the well established technology of liquid crystals display, our results shown here pave a key step for the practical application of distinct device paradigms based on magnetoelectric effect, including electric field-controlled magnetic data storage, transducers, attenuators, and spintronics.
