摘要
We report resistivity and Hall effect measurements on single crystals of the ferromagnet UCuAs2. At low temperatures ρ{variant}(T) follows a T2 law, whereas above 360 K the resistivity indicates Kondo behaviour. The Hall resistivity is positive in the whole temperature range and shows a pronounced maximum below Tc: The carrier concentration of 0.18 e-/f.u. derived from the Hall effect and the resistivity data indicates a semimetallic character of UCuAs2. The temperature variations of the ordinary and spontaneous Hall coefficients are discussed in the framework of existing theories. © 1990.
