A novel small signal equivalent circuit model is proposed in the inversion regime of metal/( ZnO ,  ZnMnO , and  ZnCoO ) semiconductor/ Si  3  N  4  insulator/p-Si semiconductor (MSIS) structures to describe the distinctive nonlinear frequency dependent capacitance ( C-F ) and conductance ( G-F ) behaviour in the frequency range from 50 Hz to 1 MHz. We modelled the fully depleted  ZnO  thin films to extract the static dielectric constant ( ε   r  ) of  ZnO ,  ZnMnO , and  ZnCoO . The extracted enhancement of static dielectric constant in magnetic n-type conducting  ZnCoO  ( ε   r   ≥ 13.0) and  ZnMnO  ( ε   r   ≥ 25.8) in comparison to unmagnetic ZnO ( ε   r   = 8.3–9.3) is related to the electrical polarizability of donor-type bound magnetic polarons ( BMP ) in the several hundred GHz range (120 GHz for  CdMnTe ). The formation of donor-BMP is enabled in n-type conducting, magnetic  ZnO  by the s-d exchange interaction between the electron spin of positively charged oxygen vacancies    \documentclass[12pt]{minimal} 				\usepackage{amsmath} 				\usepackage{wasysym}  				\usepackage{amsfonts}  				\usepackage{amssymb}  				\usepackage{amsbsy} 				\usepackage{mathrsfs} 				\usepackage{upgreek} 				\setlength{\oddsidemargin}{-69pt} 				\begin{document}$${V}_{o}^{+}$$\end{document}V    o    +in the  BMP  center and the electron spins of substitutional Mn 2+  and Co 2+  ions in  ZnMnO  and  ZnCoO , respectively. The  BMP  radius scales with the Bohr radius which is proportional to the static dielectric constant. Here we show how  BMP  overlap can be realized in magnetic  n-ZnO  by increasing its static dielectric constant and guide researchers in the field of transparent spintronics towards ferromagnetism in magnetic,  n-ZnO .
