Magnetic Moments in Ultrathin Chromium Films on Fe(100)

Absolute magnetic moments of Cr are determined from in situ magnetometer measurements during growth of ultrathin Cr films of Fe(100). Chromium moments in the first atomic layer are aligned antiparallel to the iron moments and amount to = > 4 mu sub B for submonolayer coverage and 3 mu sub B for t...

description Absolute magnetic moments of Cr are determined from in situ magnetometer measurements during growth of ultrathin Cr films of Fe(100). Chromium moments in the first atomic layer are aligned antiparallel to the iron moments and amount to = > 4 mu sub B for submonolayer coverage and 3 mu sub 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.
