From: Correlation between tunability and anisotropy in magnetoelectric voltage tunable inductor (VTI)
Tunability of ferrite VTI. (a) Inductance spectra of ring-type ferrite/PMN-PZT VTI. (b) Tunability γ of ring-type ferrite/PMN-PZT VTI under different electric field at 100 kHz. Frequency dependence of tunability of (c) NiZnCu-ferrite/PMN-PZT and (d) Metglas/PMN-PZT VTI. A significant contrast in the frequency dependence of ferrite vs. Metglas based composites can be noticed. Metglas based composites exhibit rapid decay in tunability with frequency while the ferrite based composites have almost flat response until MHz range.
