Abstract

We report a study of the critical behavior of the resistivity in n-type (In-doped) and p-type (Ag-doped) CdCr₂Se₄ single crystals. The results are analyzed in terms of the various proposed band models. We conclude that the valence band is a wide band with a small exchange interaction between the carrier and the localized spins. The conduction band is a narrow band, the broadening of which yields the enhancement of the mobility in the ferromagnetic region.
