Magnetic Order and Fermi Surface in CeAs

Abstract

The experimental result of the de Haas van Alphen effectin CeAs is critically reexamined based on the magnetic polaron liquidand lattice model, to be consistent with other properties. It is shownthat, in contradiction to the claim that a large hole Fermi surface isnot observed, all the Fermi surfaces are observed satisfying theelectron-hole compensation, when the magnetic order, which is inducedthrough the magnetic polaron lattice, under applied magnetic field istaken into account. Other properties are also explainedconsistently. It is noted that the same situation exists for YbAs.
