Title: Magnetotransport in the low carrier density ferromagnet EuB{sub 6}

Abstract

We present a magnetotransport study of the low-carrier density ferromagnet EuB{sub 6}. This semimetallic compound, which undergoes two ferromagnetic transitions at T{sub l}=15.3 K and T{sub c}=12.5 K, exhibits close to T{sub l} a colossal magnetoresistivity (CMR). We quantitatively compare our data to recent theoretical work, which, however, fails to explain our observations. We attribute this disagreement with theory to the unique type of magnetic polaron formation in EuB{sub 6}. (c) 2000 American Institute of Physics.
