Comparison of magnetic properties of nanopowders of carbon-doped and pure ZnO prepared by pulsed electron beam evaporation

The abnormal behavior of the ZnO-C (% xC = 0.25 wt%) sample magnetization curve in the magnetic field of 2.4 T can be attributed to the metamagnetic transformation associated with the bimodal distribution of the ZnO ferromagnetic phase in accordance with the SEM analysis.
