Magnetic properties of NCZF-CFO materials. a Frequency dependence of the real part of permeability, μ′, of NCZF-100xCFO. b Frequency dependence of the imaginary part of permeability, μ″, of NCZF-100xCFO. c Permeability comparison between NCZF-2CFO and commercial high-frequency ferrite Ferroxcube 4F1. d Loss factor \({\rm{tan}}\delta /\mu \prime = \mu \prime\prime {\mathrm{/}}(\mu \prime\prime )^2\) comparison among different ferrite compositions. e Magnetization vs. magnetic field loops of NCZF-100xCFO. f Saturation magnetization \(\left| {\lambda _{\mathrm{s}}} \right|\) of NCZF-100xCFO. \(\left| {\lambda _{\mathrm{s}}} \right| = \frac{2}{3}\left( {\left| {\lambda _{11}} \right| + \left| {\lambda _{12}} \right|} \right)\), where λ11 is the longitudinal magnetostriction measured when the strain gauge was parallel to the magnetic field, and λ12 is the transverse magnetostriction measured when the strain gauge was perpendicular to the magnetic field. The data point of \(\left| {\lambda _{\mathrm{s}}} \right|\) for pure CFO (x = 1) refers to prior study (Ref. 24)
