Summary

Descripción general del contenido del recurso.

We have studied the influence of intrinsic and extrinsic defects in the magnetic and electrical transport properties of Co-doped ZnO thin films. X-ray absorption measurements show that Co substitute Zn in the ZnO structure and it is in the 2? oxidation state. Magnetization (M) measurements show that doped samples are mainly paramagnetic. From M vs. H loops measured at 5 K we found that the values of the orbital L and spin S numbers are between 1 and 1.3 for L and S = 3/2, in agreement with the representative values for isolated Co 2?. The obtained negative values of the Curie?Weiss temperatures indicate the existence of antiferromagnetic interactions between transition metal atoms. Fil: Golmar, Federico.
