The temperature dependence of the thermodynamic properties of uranium compounds

The mean field equations have been solved for an Anderson lattice corresponding to a uranium heavy fermion compound as a function of temperature, both numerically and using an analytic approximation for the Fermi function. We find that the analytic results are a good approximation to the numerical results and also give a good physical insight into the nature of the solution. We calculate the magnetic suceptibility as a function of temperature and compare the results with UPt3. (orig.)
