“…YbCu:Si 2 crystallizes in the tetragonal body-centered ThCr2Si:-type structure [2] and is characterized as an intermediate valence compound reflecting the strong hybridization between the 4f localized electrons and the conduction band electrons [3]. YbCuESi 2 is shown to be a nonmagnetic compound down to 0.05 K [4] with a large ,/-value of 210 mJ/mol K 2 [5]. It is well known that the hybridization is very sensitive to external forces such as pressure, temperature and magnetic field.…”

In this paper, we introduce a microscopic theory for the heavy-fermion metals under applied pressure in the framework of the slave-boson mean-field approximation of the U = oo Anderson lattice model. The density of states for f electrons and its variation with the pressure are caicuiated self-consistently. The pressure-dependencies of the low-temperature specific-heat coefficient, magnetic susceptibility, and the resistivity in the electron-type and hole-type heavy-fermion metals are obtained. The results provide a unified explanation on the two opposite pressure-dependent effects observed in Ce-based and Yb-based compounds.

“…Previously we have shown [6] that pressure modifies the temperature dependence of the resistivity to of pure UBe13, particularly at low temperatures where p reaches a maximum at T = Tma ~ --2.5 K. Further, there appears to be an inverse correlation [7] between Tm~ and the pressure dependent electronic specific heat y(P), i.e. ~,(P) (x I/Tm~(P ).…”
