Abstract
The energy of infared and millimeter radiation is well suited to elementary excitations in solids and provide in this way an excellent tool to investigate the corresponding physical mechanism by resonant and nonresonant spectroscopy. Due to the large number of competing transitions caused by different physical processes the experimentalist envisages quite often the problem to identify correctly the resonance structure in question. Magnons, quasi-free carrier transitions, phonons and impurity excitations superimpose within the spectrum of experimental data. This means that there is need for a filter to discriminate the transition in question from the other perturbing effects. In many cases magnetic fields provide this filter function, if the energy levels involved can be tuned by those fields.
