Light controlled magnetoresistance and magnetic field controlled photoresistance in CoFe film deposited on BiFeO3

B. Kundys, C. Meny, M. R. J. Gibbs +5

We present a magnetoresistive-photoresistive device based on the interaction of a piezomagnetic CoFe thin film with a photostrictive BiFeO3 substrate that undergoes light-induced s…
