✦ Synopsis

Considering the fact that the hybridization bands of the two spins are shifted differently by the Zeeman energy, we adopt a two-"band" model to study the field dependence of the anomalous Hall resistance of the heavy-fermion compounds. Starting from the periodic Anderson Hamiltonian, we use the standard large-degeneracy expansion for the slave-boson technique. At the mean-field level, we find that the anisotropy of the hybridization matri ~ element is crucial in reproducing the correct field dependence of the Hall resistance. This provides further evidence for t ~e feasibility of our previously proposed mechanism for the metamagnetic-like transition.
