Nature of the magnetic ground state in the mixed valence compound CeRuSn: a single-crystal study

Original language description

We report on detailed low-temperature measurements of the magnetization, the specific heat and the electrical resistivity on high-quality CeRuSn single crystals. The compound orders antiferromagnetically at T-N = 2.8 K with the Ce3+ ions locked within the a-c plane of the monoclinic structure. Magnetization shows that below T-N CeRuSn undergoes a metamagnetic transition when applying a magnetic field of 1.5 and 0.8 T along the a-and c-axis, respectively. This transition manifests in a tremendous negative jump of similar to 25% in the magnetoresistance. The value of the saturated magnetization along the easy magnetization direction (c-axis) and the magnetic entropy above T-N derived from specific heat data correspond to the scenario of only one third ofthe Ce ions in the compound being trivalent and carrying a stable Ce3+ magnetic moment, whereas the other two thirds of the Ce ions are in a nonmagnetic tetravalent and/or mixed valence state. This is consistent with the low-temperature
