From: Increased static dielectric constant in ZnMnO and ZnCoO thin films with bound magnetic polarons
Real part (ε1) of dielectric constant for (a) ZnO, (c) Zn0.95Co0.05O, Zn0.95Mn0.05O, and (e) Zn0.98Co0.02O, Zn0.98Mn0.02O has been estimated by applying Kramers-Kronig tranformation to imaginary part (ε2) of dielectric constant for (b) ZnO, (d) Zn0.95Co0.05O, Zn0.95Mn0.05O, and (f) Zn0.98Co0.02O, Zn0.98Mn0.02O, respectively. The electronic44 and phonon43 contribution to ε2 has been taken from literature43,44. An additional contribution to ε2 due to BMP at 120 GHz has been assumed in such a way that ε1 agrees with modelled εr.
