High-Q magnetoelectric nickel–quartz–nickel structures

The results of experimental examination of the magnetoelectric parameters of three-layer nickel–quartz–nickel structures in the region of electromechanical resonance are presented. The structures have been fabricated by electrolytic deposition of nickel onto a quartz substrate. It has been found that their Q-factor in the region of electromechanical resonance is $Q$ = 10000, which is considerably higher than the Q-factors of magnetoelectric structures fabricated earlier. The experimental data agree well with the earlier-presented theory.
