dc.description.abstract | We present magnetization and resistivity measurements on single crystals of yttrium doped with small concentrations of gadolinium (c = 1, 2, and 3 at. %). The low-field susceptibility exhibits a spin-glass-like sharp cusp for the magnetic field along the e axis. However, there is no irreversible behavior below the temperature of the cusp, which rules out the existence of a spin-glass state. Moreover, our magnetization measurements show up a spin-flop transition for H in the basal plane. The existence of a long-range ordering is confirmed by our resistivity measurements. The resistivity parallel to the e axis exhibits a maximum just below the ordering temperature, which is reminiscent of the superzone effects observed in many rare-earth metals. The antiferromagneticlike properties of the Y Gd alloys contrast with the spin-glass behavior observed in other Y-rare-earth alloys at similar concentrations. | en |
