AbstractAbstract
[en] Magnetization, specific heat, and electrical resistivity measurements were made on single crystals of the filled skutterudite compound PrOs4As12. Specific heat measurements indicate an electronic specific heat coefficient γ ∼ 50-200 mJ/mol K2 at temperatures 10 K (le) T (le) 18 K, and ∼ 1 J/mol K2 for t (le) 1.6 K. Magnetization, specific heat, and electrical resistivity measurements reveal the presence of two, or possibly three, ordered phases at temperatures below ∼ 2.3 K and in fields below ∼ 3 T. The low temperature phase displays antiferromagnetic characteristics, while the nature of the ordering in the other phase(s) has yet to be determined

AbstractAbstract
[en] The low-temperature specific heat csub(p) of single-crystalline samples of USb and UTe have been measured between 0.1 and 12 K. From the experimental data values are deduced for the electronic specific-heat parameter γ of 0.2 mJ/mole K2 and 10.3 mJ/mole K2 for USb and UTe, respectively. csub(p) data below 1 K reveal the onset of nuclear specific heat with decreasing temperature. In our temperature range, this contribution is much stronger for USb than for UTe. (author)

AbstractAbstract
[en] A new method for measuring heat capacities of small samples (approximately equal to mg) at low temperatures (2-10 K) using an AC heating has been described. The incoming pulse has a special time dependence and under some circumstances gives a linear response. It is possible (on the basis of this linear response) to calculate the sample heat capacity from two independent results of the solution of the analogeous differential equation

AbstractAbstract
[en] We study the heat capacity Cs and the superfluid density ρs for the various possible order parameters in Sr2RuO4. We focus on the question of how the different nodal structures of the gap can be distinguished by the temperature dependences of the heat capacity and the superfluid density. The order parameters are classified into several different types, depending on the low temperature behavior of Cs and ρs. We also derive the general expressions for the various physical quantities while taking into account the effect of impurity scattering. Impurity scattering in the unitarity limit can have a profound effect on the physical quantities at zero temperature

AbstractAbstract
[en] The heat capacity of technetium has been measured in zero field between 3 and 15 K. A superconducting transition temperature T/subc/ = 7.86 K is found. The electronic heat-capacity coefficient and zero-degree Debye temperature are 4.30 mJ/mole K2 and 454 K, respectively. An electron-phonon enhancement factor of 0.65 is found from the McMillan equation. The thermodynamic properties of the superconducting state also indicate that technetium is an intermediate-coupling superconductor

AbstractAbstract
[en] We have measured the field-dependent heat capacity in the tetragonal antiferromagnets CeRhIn5 and Ce2RhIn8, both of which have an enhanced value of the electronic specific heat coefficient γ∼400 mJ/mol Ce K2 above TN. For T< TN, the specific heat data at zero applied magnetic field are consistent with the existence of an anisotropic spin-density wave opening a gap in the Fermi surface for CeRhIn5, while Ce2RhIn8 shows behavior consistent with a simple antiferromagnetic magnon. From these results, the magnetic structure, in a manner similar to the crystal structure, appears more two dimensional in CeRhIn5 than in Ce2RhIn8 where only about 12% of the Fermi surface remains ungapped relative to 92% for Ce2RhIn8. When B||c, both compounds behave in a manner expected for heavy-fermion systems as both TN and the electronic heat capacity decrease as field is applied. When the field is applied in the tetragonal basal plane (B||a), CeRhIn5 and Ce2RhIn8 have very similar phase diagrams which contain both first- and second-order field-induced magnetic transitions

AbstractAbstract
[en] The results on the thermal variation of Ce L3-valence in CeT2(Si1-xGex)2 series with 0(le)x(le)1 and T=Mn and Ni are reported. It is observed that for both series, the Ce valence increases with decreasing temperature and has little thermal variation for samples in the nearly trivalent regime. The magnitude of this thermal variation in the T=Mn series is much greater than in the T=Ni series. The results are explained by the degenerate Anderson model and correlated with the specific heat data.
