From Termination Dependent Chemical Sensitivity of Spin Orientation in All-bcc Fe/Co Magnetic Superlattices toward the Concept of an Artificial Surface of a Ferromagnet
Adsorption of gases on the surface of all-bcc (Fe/Co) N superlattices drives the in-plane, 90° magnetization rotation of the bulk-like Fe(110) supporting ferromagnet. Both experimental and theoretical results prove that terminating the surface of (Fe/Co) N superlattices either by Co or by Fe switche...

Summary: | Adsorption of gases on the surface of all-bcc (Fe/Co)
N
superlattices drives the in-plane, 90° magnetization
rotation
of the bulk-like Fe(110) supporting ferromagnet. Both experimental
and theoretical results prove that terminating the surface of (Fe/Co)
N
superlattices either by Co or by Fe switches “ON”
or “OFF” the spin orientation sensitivity to adsorption.
Results indicate that purely surface limited adsorption processes
strongly modify the magnetic anisotropy of the entire (Fe/Co)
N
superlattice, which acts as a kind of “artificial”
surface of the bulky Fe(110) ferromagnet. Such an artificial magnetic
surface anisotropy concept not only enhances the surface contribution
in classical surface–bulk competition but also provides its
additional chemical sensitivity. |
