Abstract:
This paper reports the development of a methodology combining microstrip ferromagnetic resonance and digital image correlation in order to simultaneously measure the voltage-induced strains and the magnetic resonance in artificial magnetoelectric heterostructures ("magnetic films/piezoelectric substrate" or "magnetic films/flexible substrate/piezoelectric actuator"). The overall principle of the technique and the related analytical modelling are described. It is powerful to estimate the magnetostriction coefficient of ferromagnetic thin films and can be used to determine the effective magnetoelectric coefficient of the whole heterostructures in addition to the piezoelectric coefficient related to the in-plane voltage-induced strains. This methodology can be applied to system for which the strains are well transmitted at the different interfaces.
