Exchange bias and nanoparticle magnetic stability in Co-CoO composites
TL;DR: In this article, a series of Co{sub x}(CoO){sub 1-x} thin films have been synthesized by sputtering Co in an oxygen atmosphere using different rf sputtering powers as a means to vary the concentration x.

Influence of spacer layer morphology on the exchange-bias properties of reactively sputtered Co ∕ Ag multilayers
Peter S. Normile,J. A. De Toro,T. Muñoz,J. A. González,J. P. Andrés,P. Muñiz,R. E. Galindo,J. M. Riveiro +7 more
TL;DR: In this article, the magnetic properties of multilayers grown in an oxygen atmosphere were studied, and it was concluded that a transition from continuous to island-like silver layers (on reducing the oxidized fraction of Co layers) is signaled by electrical resistivity and x-ray reflectivity results.

Oxygen-assisted control of surface morphology in nonepitaxial sputter growth of Ag
TL;DR: The surface roughness of Ag films (thickness of 50nm) is drastically reduced from 2.4to 1.0nm by the presence of oxygen (pressure of 2×10−5mbar) during sputter growth, without a change (undermining) in electrical transport properties nor a formation of any Ag oxide phase as discussed by the authors.

Exchange-bias stabilization of the magnetic nanoparticles in a granular alloy grown by reactive sputtering
TL;DR: In this paper, the superparamagnetic blocking temperature of a series of granular Co22Ag78 alloys grown by reactive sputtering under oxygen atmosphere exhibits a minimum when plotted as a function of the oxygen pressure.

Improvement of magnetic particle stability upon annealing in an exchange-biased nanogranular system
Peter S. Normile,J. A. De Toro,J. P. Andrés,J. A. González,T. Muñoz,P. Muñiz,Antonio J. Barbero,J. M. Riveiro +7 more
TL;DR: In this paper, the exchange bias onset temperature increases in close correlation with the average superparamagnetic blocking temperature of the magnetic particles, which is explained in terms of two structural relaxation processes previously characterized in simple Co∕Ag granular alloys: segregation of Co solute atoms from the Ag-rich matrix and particle coarsening.
