Synchrotron Radiation-Based Mossbauer Techniques

In this section, an introduction into the most common synchrotron radiation Mossbauer techniques is given emphasizing on the applications to thin films. A detailed elaboration of the methods can be found elsewhere [21,22,38]. 

Each of these processes is considered separately below. Selected examples of relevant in situ experiments on thin films illustrating the capabilities of the techniques are presented and discussed.

Although hyperfine interaction studies with both radioactive sources and synchrotron radiation have their respective advantages, new techniques based on synchrotron radiation widen the possibilities for studying hyperfine interactions and open up new prospects to perform studies that are out of the reach of conventional Mossbauer spectroscopy. 

Abstract This chapter describes a general introduction of the Mossbauer spectroscopy. What is the Mossbauer effect and what is the characteristic feature of the Mossbauer spectroscopy These questions are answered briefly in this chapter. Mossbauer spectroscopy is based on recoilless emission and resonant absorption of gamma radiation by atomic nuclei. Since the electric and magnetic hyperfine interactions of Mossbauer probe atom in solids can be described from the Mossbauer spectra, the essence of experiments, the hyperfine interactions and the spectral line shape are discussed. In addition, the experiments and the new resonance technique with synchrotron radiation have been also briefly described.
