摘要：
We report on a low-temperature magnetovolume study of single-crystalline heavy-fermion CeCu6. Magnetostriction data (B parallel-to c) taken at temperatures below 100 mK reveal two distinct anomalies at B1 = 2.2 T and B2 = 4.0 T, that are rapidly washed out by increasing the temperature. Thermal expansion measurements in fields up to 8 T (B parallel-to c) reveal an anomalous field suppression of the term linear in temperature. The fields B1 and B2 are likely related to a change in magnetic correlations. Their interrelation is investigated by a scaling approach.
