Abstract

We report experimental results on electrical control of magnetic remanent states (i.e., nanoscale remanent domain patterns) in a magnetoelectric layered nanostructure, Ni nanobar/lead zirconate titanate film. First, with application of different external magnetic fields as a baseline characterization, the magnetic single domain in the Ni nanobar presents time-dependent nanoscale remanent domain patterns which were observed under a magnetic force microscope. Based on this baseline characterization, we further successfully demonstrate that these time-dependent nanoscale magnetic domain patterns could be instantaneously controlled with an application of electric fields due to the converse magnetoelectric effect. The magnetic-field-induced changes are correlated with the electric-field-induced changes.
