Opis:: We report on the study of the electron-quasiparticle interaction function in Ce$\text{}_{1-x}$RE$\text{}_{x}$ Ni$\text{}_{5}$ (RE = Pr, Nd) pseudobinary compounds for x = 0, 0.2, 0.5, 0.8, and 1 measured by means of point-contact spectroscopy. The measured point-contact spectra (d$\text{}^{2}$V/dI$\text{}^{2}$ - directly proportional to the electron- quasiparticle interaction function) of the heterocontacts between Ce$\text{}_{1-x}$ RE$\text{}_{x}$Ni$\text{}_{5}$ and Cu in the ballistic regime are presented.zapisz i p

Opis:: The results of the measurements of temperature dependence of the electrical resistivity ρ(T), thermal expansion L(T) and susceptibility χ(T) on single crystal DyNi$\text{}_{5}$ in the temperature range 4.2-300 K are reported. The maximum in ρ(T) at T$\text{}_{N}$=12.2 K was observed which corresponds to the transition to antiferromagnetically ordered state. Taking into account the Bloch-Grüneisen formula for electron-phonon contribution ρ$\text{}_{ph}$(T) to ρ(T) the anisotropic magnetic contribution ρ$\text{}_{mag}$(T) was determined. We also observed the anisotropic behaviour of L(T) at low temperatures.

Opis:: The relation between the density of states at the Fermi level and the sign of the indirect coupling in metallic systems is revisited in the framework of a simple model recently outlined by the authors. It is shown that high density of states tends to favor ferromagnetic structures. Some examples which support this idea are indicated. Finally we develop a phenomenological explanation for the antiferromagnetic → ferromagnetic transition induced by heating equiatomic FeRh. The transition is analysed in terms of the increase in the density of states produced by the giant volume expansion associated with the ferromagnetic phase.
