Mössbauer spectroscopy is a unique method for straightforward observation of the structural and magnetic properties of the studied material. The method is based on the Mössbauer effect. The measurements result in spectra that reflect the local surroundings of the element under investigation through so-called hyperfine interactions, which influence the arrangement of the nuclear levels of the element under investigation. These spectra can be measured under a variety of conditions, but generally at very low temperatures and very strong external magnetic fields, the Mössbauer effect is more observable and the spectra more readable. This lecture describes the Mössbauer effect, the principle of measurement and some examples of measured spectra are also ilustrated.
