Influence of Hydrogen Adsorption on the Electron Spin Polarization (esp) at a Ferromagnetic (i 10)-nickel Surface
نویسندگان
چکیده
The ESP determined through electron capture by small angle reflection of deuterons at well oriented Ni(110)surfaces is found to be influenced by H 2 adsorption. A coverage of one monolayer reduces the ESP from -96 -+ 3% to -8 ± 3%. The sign indicates predominance of minority spin electrons. Desorption of hydrogen from the nickel surface restores the original polarization measured at a clean (110) nickel surface.

The electron spin polarization (ESP) at surfaces of bulk and thin film ferromagnetic materials has been investigated using electron capture spectroscopy (ECS), which probes the ESP of the topmost surface layer. At surfaces of PtMnSb, Tb and Fe,,B,,, we find nonhero ESP due to long-ranged or short-ranged ferromagnetic order. The sign of the ESP at surfaces of the Heusler alloy PtMnSb is in agree...

The spin-polarized calculations in generalized gradient approximation density–functional theory (GGA–DFT) have been used to show how the existence of second metals can modify the atomic hydrogen adsorption on Au (100), Cu (100), and Pt (100) surfaces. The computed adsorption energies for the atomic hydrogen adsorbed at the surface coverage of 0.125 ML (monolayer) for the monometallic Au (100), ...
