[en] We report very detailed measurements of the magnetoresistance (MR) in the vicinity (±5 K) of the spin reorientation temperature (TSR) for pure Gd and Gd1-xYx single crystals with x=0.025 and 0.075. The temperature dependence of the a-axis magnetoresistance in pure Gd is always negative in the temperature range studied. In the dilute Gd-Y samples the low-field MR changes from negative above TSR to positive for T< TSR, becoming again negative below some lower temperature T*, where another phase transition takes place
