[Atomic and electronic structure of metals and alloys: Clean surfaces and chemisorbed molecules]
Ultrapure Tb was further purified and surface cleaning procedures developed for basal plane and (11[bar 2]0) surface of Tb. Structure of both surfaces was found to be relaxed: (0001) is contracted by 3.9% in the first and expanded by 1.4% in second interlayer spacing; (11[bar 2]0) is contracted by 3.3% in first layer and shows a change in registry. Thin films of Gd, Tb, Dy, Ho, and Er were grown on W[l brace]110[r brace] substrate in ultrahigh vacuum. Studies have been carried out on epitaxial systems involving Cu, Fe and Mn on Fe and Pt, Cu, and Pd substrates, respectively; new metastable crystalline phases have been found. Studies of possible ferromagnetism in 4d elements (Rh, Ru) and relativistic effects in electron band structure of Cu[l brace]111[r brace] have been completed and published. Plans for the following year are given.
