Use of spin-polarized LEED rotation curves to study disordered surfaces: W(001)−(1 × 1) and W(001)−2H(1 × 1)

Extensive data sets of spin-polarized low energy electron diffraction (SPLEED) rotation curves from the clean W(001)−(1 × 1) and hydrogen-saturated W(001)−(1 × 1) and W(001)−2H(1 × 1) surfaces are presented. These represent the first simultaneous LEED measurements of two components of the electron spin polarization and diffracted intensity on any system. These measurements should be more sensitive to the disorder of the surface layer of clean …
