Dynamical Properties

We review recent work on the so-called kicked Harper model, which can be viewed either as a model system in the framework of quantum chaos, or as a pulsed version of the Harper model, which has been thoroughly investigated in the context of magnetic field effects in solid state physics. In particular we describe its rich phase diagram, by means of both dynamical methods and multifractal analysis of the spectrum.

Good Agreement

Radio-frequency methods are used to determine the variation with applied magnetic field (up to 7T) of the adiabatic susceptibility of the Van Vleck electronic paramagnet HoV0 4 , and the magnetic specific heat of the enhanced nuclear system 165HoV0 4 . The results are in good agreement with values deduced from optical measurements (Battison et al . 1977) and n.m.r. measurements (Bleaney et al . 1978).

Low Temperature Specific Heat

Specific-heat measurements on single-crystalline samples of U ( Pt 1− x Pd x )3 ( x = 0.00, 0.05 and 0.10) reveal anomalously large values for c/T at low temperatures. The data for UPt 3 have previously been analyzed by making use of the enhanced value of the low-temperature Grüneisen parameter. By this analysis, the heavy-electron contribution to the specific heat has been separated from the normal part that is largely due to the phonon term. Taking this latter term to be the same for all three compounds, the heavy-electron contribution has been evaluated for temperatures below 20 K. This contribution is compared with a spin-1/2 Kondo-type of specific heat. The resulting curves for the x = 0.00 and x = 0.10 alloys are very similar and mainly differ in the temperature at which the maximum is found. The effect of an applied magnetic field within the hexagonal plane, however, shifts the maximum to lower temperatures for x = 0.00 whereas for x = 0.10 a shift towards higher temperatures is found.

Strong Coupling Superconductor

ABSTRACTWe have measured the specific heat of κ-(BEDT-TTF)2Cu(NCS)2 from 4 to 14 K. The superconducting transition at 9.4 K is observed in zero applied magnetic field and in a field of 0.3 T. Both the magnitude of the change in Cp at Tc and the temperature dependence of Cp below Tc indicate a strong coupling superconductor. If the lattice specific heat is assumed to contain contributions due to the eighteen vibrational degrees of freedom, the phonon contribution to the specific heat in our temperature range can be represented by a Debye integral expression with a Debye temperature of 95 K. A model of collective modes suggesting the origin of the eighteen degrees of freedom is presented.
