Bias magnetic field and frequency dependence. a Magnetoelectric (ME) coupling coefficient α ME of ME NPR as functions of DC bias magnetic field H DC(x-axis) and the frequency of RF magnetic field (y-axis). The dashed curve exhibits the resonance frequency (highest intensity at each frequency sweep) versus the bias magnetic field. The bias magnetic field was swept from −5 to 5 mT. b The hysteresis loop of α ME obtained by sweeping the magnetic field back and force at f = 60.7 MHz. The inset shows the schematic representation of the ME NPR with the external bias magnetic field applied along its length direction. c Induced ME voltage as a function of magnetic field at excitation frequency of 60.7 MHz (red) and 1 MHz (blue)
