dc.description.abstract | Compositional, microstructural, and magnetic characterization of ZnO 30 Å/Mn x n multilayers
prepared by sputtering is presented to study the observed ferromagnetism in the Mn-ZnO system.
The nominal Mn layer thickness, x, is varied from 3 to 60 Å, while the number of bilayers, n, is
increased to maintain the total amount of Mn constant. Microstructure information was deduced
from x-ray reflectivity, Mn oxidation state was determined by x-ray absorption spectroscopy, and
magnetic properties were measured over a temperature range of 5–400 K. Magnetic behavior of
these samples is found to be related to the Mn layer thickness x. Multilayers with x 30 Å exhibit
ferromagnetism with a Curie temperature above 400 K, while mostly paramagnetic behavior is
obtained for x15 Å. Magnetic behavior is discussed in terms of electronic and structural
parameters of samples. Mn-ZnO interface effect is related to the ferromagnetic order of the samples,
but it is not a sufficient condition. The essential role of the Mn oxidation state in the magnetic
behavior of this system is pointed out. It is shown a correlation between the obtained
ferromagnetism and a Mn oxidation state close to 2+. | es |
