Mossbauer Studies of Surface Layers (Hardcover)

Mossbauer spectroscopy has evolved as one of the few methods available for investigation of solids differing in depth by several orders of magnitude. This recent development has made the problems of surface investigation and the study of separate layers amenable to investigation. The parameters of the hyperfine interaction derived from the Mossbauer spectra provide valuable information on the chemical bond character and on magnetic properties of surface layers as well as on the change of the properties with the depth from the outermost surface layers. It is possible to carry out quantitative phase analysis and to use the technique to study different transformations in the solid which result from external effects under a wide range of temperatures and pressures. This book is an attempt at a consistent presentation of theoretical and practical problems of the use of Mossbauer spectroscopy to study solid surfaces, its applications and development. The applications include surface studies with hyperfine probes in the following fields: oxidation and corrosion of metals and alloys; passivating and protective coatings; physics of metals; annealing and quenching, mechanical and chemical treatment, ion implanation and laser treatment; and texture of near-surface layers. Mossbauer spectroscopy is one of the best methods for in situ characterization of solid-solid and solid-solution interfaces. It lends itself to in situ studies of surfaces under various coatings and processes, surface magnetism and the effect of the gas phase on the properties of the surface layers and the structures and magnetic properties of epitaxially grown monolayers on the surface of oriented single crystals.
