[en] We discuss measurements of the susceptibility, specific heat, and transport properties (electrical and thermal resistivity, thermoelectric power) performed on polycrystalline UAl₂ samples. Despite the high disorder of the samples, we observed anomalies in the various quantities, which are believed to be intrinsic to UAl₂. Most of these anomalies can be interpreted with the existence of a narrow 5f band at the Fermi level and of paramagnon excitations within this 5f band

[en] Specific heat measurements are reported on a CeAl₂ single crystal between 0.02 and 1 K. Above 0.08 K results were in good agreement with previous results above 0.3 K. Below 0.08 K, an excess specific heat was detected and interpreted in terms of hyperfine splitting of the Al²⁷ nuclear states. The results suggest that in CeAl₂ (complex) antiferromagnetism coexists with the Kondo effect at least down to 20 mK. (author)

[en] We have analyzed data from existing accurate pressure and molar volume measurements of ³He along the melting curve to determine explicit entropy contributions of the liquid and solid phases. Below 300 mK there is a significant discrepancy between the melting curve data of Grilly and Halperin, et al. The resolution of this problem is the subject of this paper. We find that zero sound makes an important contribution to the liquid entropy and that the superfluid ³He A-transition temperature must be shifted upward. (orig.)

[en] Values of the electrical resistivity, temperature coefficient of resistivity, thermopower, and superconducting transition temperature for a series of La/sub 100-//sub x/Al/sub x/ metallic glasses prepared both as ''splat-cooled'' foils and ''melt-spun'' ribbons are reported. Differences between the two types of samples are discussed. We argue that the dominant contribution to the conductivity and thermopower is from La d states
