چکیده
An elastic anomaly, observed in the heavy Fermi liquid state of Ce alloys (for example, CeCu6 and CeTe), is analyzed by using the infinite-U Anderson lattice model. Four atomic energy levels are assumed for f-electrons. Two of them are mutually degenerate. A small crystalline splitting 2∆ is assumed between two energy levels. Fourfold degenerate conduction bands are also considered. We solve the model using the mean field approximation to slave Permanent address: Fundamental Physics Section, Electrotechnical Laboratory, Umezono 1-1-4, Tsukuba, Ibaraki 305, Japan; E-mail address: [email protected].

متن کاملTheory of an elastic anomaly in the heavy fermion system CeTe
The elastic anomaly observed in the coherent Kondo state of Ce heavy fermion compounds is analyzed by using the Anderson lattice model simulating the energy level scheme of CeTe. The Γ7 doublets and Γ8 quartets of the 4f states are considered in the model. We solve the mean field equations to derive the temperature dependences of elastic constants, using the random phase approximation like expr...
متن کاملEvolution of the heavy fermion state in Ce2IrIn8
We report μSR Knight shift and susceptibility studies for 1 T applied field along the crystalline cand a-axes of the heavy fermion compound Ce2IrIn8. Below a characteristic temperature T ∗ one observes a ‘Knight-shift anomaly’ in which the Knight shift constant K no longer scales linearly with χ. This anomaly is consistent with a scaling law in which the susceptibility χ is composed of a high-t...

We report on extensive elastic neutron scattering to determine the wave vector of the magnetic order in CeCu6−xAux single crystals for x > 0.1. For all values of x investigated (0.2, 0.3, 0.5, 1.0) we find long-range incommensurate antiferromagnetic order with an ordering vector Q ≈ (0.625 0 0.275) for x = 0.2, nearly unchanged for x = 0.3, and Q ≈ (0.59 0 0) for x = 0.5, staying roughly the sa...
متن کاملNeutron 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 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 ...
