Neutron diffraction study of magnetic field induced behavior in the heavy Fermion Ce3CO4Sn13

Neutron diffraction study of magnetic field induced behavior in the heavy Fermion Ce3CO4Sn13
The specific heat of Ce3Co4Sn13 exhibits a crossover from heavy Fermion behavior with antiferromagnetic correlations at low field to single impurity Kondo behavior above 2 T. We have performed neutron diffraction measurements in magnetic fields up to 6 T on single crystal samples. The (0 0 1) position shows a dramatic increase in intensity in field which appears to arise from static polarization of the 4f level and which at 0.14 K also exhibits an anomaly near 2 T reflecting the crossover to single impurity behavior.

Abstract

The specific heat of Ce3Co4Sn13 exhibits a crossover from heavy Fermion behavior with antiferromagnetic correlations at low field to single impurity Kondo behavior above 2 T. We have performed neutron diffraction measurements in magnetic fields up to 6 T on single crystal samples. The (0 0 1) position shows a dramatic increase in intensity in field which appears to arise from static polarization of the 4f level and which at 0.14 K also exhibits an anomaly near 2 T reflecting the crossover to single impurity behavior.
