Abstract:

(Fe1-xCox)(49)Rh-51 compounds with x = 0 divided by 0.1 have been studied by means of the electrical resistivity and magnetization measurements. The substitution of Fe for Co atoms up to 3.5 at. \% decreases the critical ferro-antiferromagnetic (F-AF) transition temperature T-t. At x greater than or equal to 0.035 only the ferromagnetic order exists in these compounds as well as in the (Fe1-xNix)Rh system. The field induced AF-F transitions at T < T-t in (Fe1-xCox)(49)Rh-51 are accompanied by the giant magnetoresistance effect (Delta rho/rho similar to -80 \%). The temperature dependencies of the electrical resistivity at low temperatures show the T-2 law in both the AF and F states. The coefficient A of the T-2-term depends nonmonotonously on the Go-content reaching the maximal value near the critical boundary of antiferromagnetism owing to the contribution from spin fluctuations.
