Magnetization of Fe‐oxide based nanocomposite tuned by surface charging
Source abstract
Abstract
Abstract Aiming at a voltage‐control of magnetism, the magnetization of a porous γ‐Fe2O3–Pt nanocomposite is studied under the influence of charging the surfaces of the porous structure in an electrolyte. Reversible variations of the magnetization of up to 10.4% could be achieved upon charging in the regime where electrochemical adsorption and desorption occurs. The observed variation of the magnetization with electrochemical charging is assigned to the γ‐Fe2O3 nanoparticles whereas the conductive network of Pt nanoparticles is necessary for charging.
