Abstract
A full-thickness dependent, from two monolayers to bulk, absolute determina tion of the total magnetic moments of Co/Cu(001) films is carried out ill s itu with the help of UHV high-T-c SQUID magnetometer. The total moment is e nhanced by 11% compared to the bulk value of 1.7 mu (B)/atom measured in th e thick limit. These values agree perfectly with polarized neutron diffract ion measurements for the bulk and confirm theoretical predictions for the u ltrathin limit.
