摘要：

We have calculated the field dependence of the magnetoresistance and the Hall constant for the N = 2 insulating phase of the Anderson lattice Hamiltonian using a slave-boson approach. At low temperatures, the magnetoresistance is negative and its field dependence as well as that of the Hall coefficient are in qualitative agreement with the experimental results for Ce3Bi4Pt3. At high temperatures, the magnetoresistance has a small positive quadratic field dependence. We predict an almost identical value of the transverse and longitudinal magnetoresistances for this compound at low temperatures.
