Neutron diffraction study of magnetic field induced behavior in the heavy Fermion Ce3Co4Sn13
نویسندگان
چکیده
The specific heat of Ce3Co4Sn13 exhibits a crossover from heavy Fermion behavior with antiferromagnetic correlations at low field to single impurity Kondo behavior above 2T. We have performed neutron diffraction measurements in magnetic fields up to 6T 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 0.14K also exhibits an anomaly near 2 T reflecting the crossover to single impurity behavior. r 2007 Elsevier B.V.

Low temperature behavior of the heavy fermion Ce3Co4Sn13
The compound Ce3Co4Sn13 is an extremely heavy cubic heavy fermion system with a low temperature electronic specific heat of order 4 J=molK. If the compound is nonmagnetic, it would be one of the heaviest nonmagnetic Ce-based heavy fermions reported to date and therefore would be expected to lie extremely close to a quantum critical point. However, a broad peak of unknown origin is observed at 0...
متن کاملObservation of field-induced single impurity behavior in the heavy fermion compound Ce3Co4Sn13
We have performed heat capacity measurements in magnetic fields to 90 kOe on single crystals of the cubic heavy fermion compound Ce3Co4Sn13. In zero field, there are no signs of long-range magnetic order down to 0.35K. However, C=T increases rapidly below 2K, reaching a very large maximum value of 4 J=mol Ce–K around 0.8K in zero field, and the high-field magnetic entropy approaches R ln 2 at 2...

One of the most important reactions of the URCA that lead to the cooling of a neutron star, is neutron beta-decay ( ). In this research, the energy spectra and wave functions of massive fermions taking into account the Anomalous Magnetic Moment (AMM) in the presence of a strong changed magnetic field are calculated. For this purpose, the Dirac-Pauli equation for charged and neutral fermions is ...
متن کاملSpecific heat measurements and structural investigation of CeCu(6-x)Sn(x) compounds.
The evolution of the crystal structure and some magnetic properties of the heavy-fermion material CeCu(6-x)Sn(x) (x = 0, 0.25, 0.65, 0.75, 0.85 and 1.0) has been studied by powder neutron diffraction and by specific heat measurements. The substitution of Cu by Sn suppresses the temperature induced orthorhombic to monoclinic transition, known to occur in the pure CeCu(6) phase. No structural pha...

The magnetic structure of Ce0.9La0.1RhIn5 is measured using neutron diffraction. It is identical to the incommensurate transverse spiral for CeRhIn5, with a magnetic wave vector qM = (1/2, 1/2, 0.297), a staggered moment of 0.38(2)μB at 1.4K and a reduced Néel temperature of 2.7 K.
