Abstract

Multiferroic heterostructure CoFeB/Pb(Mg_1/3Nb_2/3)O₃–PbTiO₃ is prepared by depositing CoFeB films on Pb(Mg_1/3Nb_2/3)O₃–PbTiO₃ single crystal through direct current magnetron sputtering. The electric field induced magnetism change of CoFeB film was studied by magneto-optical Kerr effect measurement. The magnetic hard/easy axis change was investigated under direct current electric field. Alternative current voltage magneto-optical Kerr effect test indicates the different magnetoelectric mechanism with the change of film thickness. The microwave frequency tunability was observed under the electric field and the tunable ferromagnetic resonance field reaches 190 Oe. Our study provides great opportunities for the application of electric-field tunable information storage devices.
