  The Kondo lattice model of spin-1/2 local moments coupled to the conduction
electrons at half-filling is studied for its orbital response to magnetic field
on bipartite lattices. Through an effective charge dynamics, in a canonical
representation of electrons that appropriately describes the Kondo insulating
ground state, the magnetization is found to show de Haas-van Alphen
oscillations from intermediate to weak Kondo coupling. These oscillations are
ascribed to Lifshitz-like inversion of a dispersion of the gapped
quasiparticles, whose chemical potential surface is measured by the oscillation
frequency. Such oscillations are also predicted to occur in spin-density wave
insulators.
