Local magnetism of ultrathin fcc-Co films on Cu(100) investigated by 111In probes

Formation of metastable phases and their effect on the magnetic properties of Co-Cu multilayers

“…When t Co reaches 90 2 the Cu concentration is reduced to 44%, which indicates that the metastable solid solution even becomes a Co-rich one for large t Co . The formation of CoCu solid solutions resembles the results observed in other groups [21][22][23][24][25]. Some different structure characteristics shown in XRD patterns for Co-Cu or Co-Ag films have been reported recently since they depend sensitively on their preparation conditions [9,21,26,27].…”

Orbital moments of 3d adatoms and Co nanostructures on Cu(001) surfaces

“…Ab initio theoretical investigation of Co wires on Cu(0 0 1) [7] have recently suggested that enhanced orbital moments can also be found in these systems. We note that in the limit of very small cobalt concentration on Cu(0 0 1), there is experimental evidence [8][9][10][11][12][13] for cobalt islands formation, which in principle could also lead to an enhancement of the orbital moment. In face of these results, the investigation of the orbital moment for 3d transition metal adatoms, and Co nanoparticles on Cu substrates, seems very relevant.…”

The Effects of Layer Thickness on the Microstructure and Magnetic Properties of Evaporated Co/Ag Films

“…For example, some metastable fcc Co phases were obtained in Co/Ag [6][7][8], Co/Pt [9], and Co/Cu [10][11][12] multilayers and granular films. Using 200 keV xenon ion mixing of nano-sized Co/Ag multilayers about 40 nm thick, metastable and fcc phases were formed at room temperature [6].…”
