Abstract

Here, we have studied theoretically the temperature dependence of magnetic susceptibility of some Heavy Fermion (HF) using the Periodic Anderson Model (PAM) and Zubarev technique. The effect of electron–phonon interaction has been considered and it is observed that the calculated magnetic susceptibility shows correct behavior as a function of temperature with existing experimental results for some U-based and Ce-based HF systems. The extrapolated Kondo temperature for UPt3 was found to give nearly the same value as observed experimentally by Frings et al (1983).
