The competition between kondo and RKKY interaction in CeTSn compounds
This article reviews our investigations of the series CeTSn where T stands for a transition element. Our research was stimulated by the unusual behavior of CeNiSn. These compounds are close to the border between magnetic and nonmagnetic Kondo systems. For the understanding of their physical properties a detailed knowledge of the magnetic properties is essential. μSR experiments allow one to reveal even weak magnetic correlations. Special attention is given to the explanation of experimental details. Pulsed (ISIS) and continuous (TRIUMF) muon beams were used as complementary techniques. Experiments in zero and longitudinal (with respect to the muon spin) applied field allowed the determination of the static width of the magnetic field distribution seen by the muons due to ionic moments as well as the fluctuation rate of the internal field. As a part of our experiments, the muon site has been determined and the procedure for this will be described.
