Field-induced quantum fluctuations in the heavy fermion superconductor CeCu2Ge2
Quantum-mechanical fluctuations in strongly correlated electron systems cause unconventional phenomena such as non-Fermi liquid behavior, and arguably high temperature superconductivity. Here we report the discovery of a field-tuned quantum critical phenomenon in stoichiometric CeCu(2)Ge(2), a spin density wave ordered heavy fermion metal that exhibits unconventional superconductivity under ≃10...
متن کاملTransport in the Heavy Fermion Superconductor UPt3
We report new theoretical results and analysis for the transport properties of superconducting UPt3 based on the leading models for the pairing symmetry. We use Fermi surface data and the measured inelastic scattering rate to show that the low-temperature thermal conductivity and transverse sound attenuation in the A and B phase of UPt3 are in excellent agreement with pairing states belonging t...

متن کاملField-induced magnetic transition in the heavy-fermion antiferromagnet Ce7Ni3
We present a detailed study of the field ~B! temperature ~T! phase diagram of the heavy-fermion antiferromagnet Ce7Ni3 that crystallizes in the hexagonal Th7Fe3-type structure with three nonequivalent Ce sites (Ce I , Ce II , and Ce III). This compound undergoes two magnetic transitions at TN151.9 K and TN250.7 K in zero field. Below TN1, an incommensurate spin density wave ~SDW! develops, and ...
متن کاملField-induced suppression of the heavy-fermion state in YbRh2Si2.
We report dc-magnetization measurements on YbRh2Si2 at temperatures down to 0.04 K, magnetic fields B< or =11.5 T, and under hydrostatic pressure P< or =1.3 GPa. At ambient pressure a kink at B* =9.9 T indicates a new type of field-induced transition from an itinerant to a localized 4f state. This transition is different from the metamagnetic transition observed in other heavy-fermion compounds...
