摘要：

Absolute magnetic moments of Cr are determined from in situ magnetometer measurements during growth of ultrathin Cr films on Fe(100). Cr moments in the first atomic layer are aligned antiparallel to the Fe moments and amount to greater-than-or-equal-to 4 mu(B) for submonolayer coverage and 3mu(B) for the first complete monolayer. This is the first experimental evidence of the huge moment enhancement predicted for Cr interfaces by band theory. Monte Carlo simulations indicate a drastic deviation from layer-antiferromagnetic order within the first 2-3 Cr atomic layers.
