TL;DR: In this paper, the transverse magnetoresistance of degenerate $n$-type Si has been measured in the liquid-helium temperature range and a characteristic negative magnetoreduction is observed.
Abstract: Transverse magnetoresistance of degenerate $n$-type Si has been measured in the liquid-helium temperature range. A characteristic negative magnetoresistance is observed. The data are analyzed by a semiempirical expression originally used for CdS by us, thus providing further evidence for the general validity of our expression and for the localized-magnetic-moment model.

TL;DR: In this article, it was shown that it is possible to obtain a negative magnetoresistance in an impurity banded semiconductor at T = 0°K, provided that the Fermi energy was located at the interband edge where a sharp mobility edge is assumed to exist.

TL;DR: The transverse and longitudinal magnetoresistance on polycrystalline d.h.c.p. as mentioned in this paper have been measured at 1.38 K and 1.4 K with applied fields up to 20 kOe.

TL;DR: Indication of localized magnetic moments in hydrogenated NiCr alloys by resistance minima and by a negative contribution to the magnetoresistance is given in this article. But this is not the case in the case of NiC alloys.
