From: Dynamical magnetic behavior of anisotropic spinel-structured ferrite for GHz technologies

Frequency dependence of dynamic permeability obtained by the MSL-probe method up to 50 GHz. The external magnetic DC field (\(H_{dc}\)) applied during the measurements is (a) 0, (b) 0.32, (c) 3.08, (d) 4.67, (e) 6.24, and (f) 7.02 kOe, respectively. (g) The relationship between \(f_{r}\) and \(H_{dc}\) based on the results form measurements with a linear fit.
