Abstract

The magnetoresistance of Gd single crystals has been investigated from 4.2 to 220 K, and in fields up to 35 T, in both longitudinal and transverse configurations. At low temperatures the magnetoresistance is positive, due to electron trajectory effects, whilst above 50 K the negative magnetoresistance arising from the suppression of spin fluctuation is evident. The anisotropy between longitudinal and transverse configurations is discussed.
