Ferromagnetic order in U(Rh,Co)Ge
arXiv:0902.0974 · doi:10.1016/j.ssc.2009.02.013
Abstract
We report the variation of ferromagnetic order in the pseudo-ternary compounds URh_{1-x}Co_{x}Ge (0 \leq x \leq 1). Magnetization and transport data taken on polycrystalline samples show that the Curie temperature T_{C} gradually increases with increasing Co content from a value of 9.5 K for URhGe to a maximum value of 20 K for x = 0.6 and then steadily decreases to 3 K for UCoGe. The magnetic interaction strength varies smoothly across the series. For all samples the electrical resistivity for T < T_{C} follows the behaviour ρ= ρ_{0} + AT^2. The A coefficient is dominated by scattering at spin waves and is strongly enhanced for x = 0 and 1.
