“…In this line, the Co-Ag system present interest because, at equilibrium, cobalt is immiscible with silver, thus giving easily sharp interfaces between the magnetic clusters and the non-magnetic matrices [7]. Preparation of Co-Ag films has been made by a variety of techniques well suited to commercial manufacture, such as molecular beam epitaxy (MBE), sputtering, laser pulsed deposition or mechanical alloying [8][9][10][11][12][13].…”
