Abstract
Fe films grown in ultrahigh vacuum onto a curved Pd(001) substrate with a c
ontinuous gradient in atomic step density were studied in situ via the surf
ace magneto-optic Kerr effect (SMOKE). The steps induce an in-plane, uniaxi
al magnetic anisotropy with the easy axis perpendicular to the step edges,
and whose strength scales linearly with step density. The Curie temperature
of 1-2 monolayers of Fe is enhanced by the steps relative to that on a fla
t substrate. The enhancement is attributed to a step-induced Pd moment at s
tep edges, as inferred from the enhancement of the SMOKE signal with step d
ensity.
