Zusammenfassung: | A tunable magnetoelectric inductor composed of a symmetrical trilayer of Ga-doped NiZn ferrite and PZT in a solenoid has been developed. Under the influence of external electric/magnetic fields, the permeability variation arising from magnetostriction and piezoelectric strain in the composite results in a bidirectional tuning of the inductance L with a maximum tunability of 571% at a lower magnetic field. The largest variation in L occurs for frequencies centered around longitudinal acoustic resonance. The dual and large tunability of L is of importance for applications in compact and power-efficient integrated circuits. |
