We have studied magnetic properties of zinc-oxide composite doped with high concentration (up to 20%) of Co and Cr ions. The pulsed laser deposition method was used to obtain samples on quartz glass and sapphire substrates. Samples were annealed at 100-250°C for ZnO on quartz substrate, and 300-700°C on sapphire substrate. EMR measurements were carried out and temperature dependence of the EMR spectra was obtained. The angular dependence in two samples orientation, vertical and horizontal, were also obtained. Analysis of the temperature dependences of the integral intensity of EMR spectra was carried out using the Curie-Weiss law.
