Experimental studies of magnetoresistance and magnetization on the degenerate magnetic semiconductor (GeTe)99(MnTe), indicate that the transport properties correlate with the square of the magnetization both above and below the ferromagnetic transition. A simple spin-flip scattering mechanism yields a value for P,~~o f 0.8 eV in agreement with the dependence of the Curie-Weias temperature on manganese concentration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
