Static and dynamic magnetization control of extrinsic multiferroics by the converse magneto-photostrictive effect

Autor: Liparo, Matthieu, Jay, Jean-Philippe, Dubreuil, Matthieu, Simon, Gaëlle, Fessant, Alain, Jahjah, Walaa, Grand, Yann Le, Sheppard, Charles, Prinsloo, Aletta R. E., Vlaminck, Vincent, Castel, Vincent, Temdie-Kom, Loic, Bourcin, Guillaume, Spenato, David, Dekadjevi, David T.

In this work, photostrictive manipulations of static and dynamic magnetic properties are demonstrated in an extrinsic multiferroic composite. The photostriction is achieved with visible light in the blue region of the spectrum. The composites consist

We conducted three experimental studies of magnetization reversal (MR) behavior in three different types of bilayers, under different types of strain. We studied the influence on the magnetic properties of the structural state in the BiFe03, of magne
