| Aim: To enable the student to investigate the composition, structure and magnetic properties of paramagnetic materials by the magnetic resonances occurring in the materials. Also, to enable the student to construct and apply the necessary equipment for measuring the magnetic resonances. |
| Contents: The course begins with an overview of electron spin resonance (ESR) and applications within solid state physics, organic chemistry and biology. A section on measuring technology deals with the construction of the ESR-spectrometer from microwave components and equipment for the detection, recording and dataprocessing of the ESR spectra. The theoretical section deals particularly with paramagnetic resonance of ions in crystal fields. In the exercises, paramagnetic and ferromagnetic resonance spectra are measured and interpreted. At the end of the course, individual experimental problems are solved by the students. The results are discussed at an oral presentation, and finally a written report explains the measurements and their interpretation. |
