Room temperature dc resistivity as a function of weight percent of lead zirconate titanate (PZT) in hot-pressed (HP) composites of nickel zinc ferrite, (NZFO), and PZT.
Bias magnetic field dependence of longitudinal (squares) and transverse (circles) magnetoelectric (ME) voltage coefficients for hot-pressed (closed symbols) and sintered (open symbols) bulk composites of NZFO -PZT with a PZT volume fraction . The transverse coefficient corresponds to and an ac field parallel to each other and to the sample plane and the induced electric field measured along the direction-3, perpendicular to sample plane. The longitudinal coefficient is for all the fields parallel to each other and along direction-3.
Maximum ME voltage coefficient at as a function of (i) volume fraction for PZT in hot-pressed NZFO -PZT samples (top) and (ii) zinc concentration in (bottom). The circles and squares represent longitudinal and transverse coefficients, respectively. The lines are a guide to the eye.
Frequency dependence of longitudinal ME voltage coefficients for hot-pressed NZFO -PZT with . The bias field was set for maximum ME coupling. The resonance frequency corresponds to the electromechanical resonance (EMR) for radial modes in the composite.
Data as in Fig. 3, but for peak ME voltage coefficients at resonance. The lines are a guide to the eye.
