Zusammenfassung
Epitaxial sesquilayers (sesqui = one and a half) of Fe(1 1 0), prepared
near room temperature on W(1 1 0), are composed of a pseudomorphic
monolayer sea which is ferromagnetically magnetized in the plane
below its Curie temperature Tc(ML) = 222 K, and a system of pseudomorphic
double layer islands which just after preparation are perpendicularly
magnetized at room temperature. During exposure to residual gas,
the double-layer islands switch to in-plane magnetization. This adsorption-driven
spin reorientation transition is studied using torsion oscillation
magnetometry (TOM), for the case of a sesquilayer consisting of 1.46
pseudomorphic layers, prepared at 325 K.
