13. min is found to be specimen-dependent (possibly due to slight non-uniform distribution of Gd in the dilute limit) for the composition x = 0.8, and it falls in the range 15-45 K. Therefore, the magnetoresistance data (fig. 2 (b)) is more instructive to infer the onset temperature of magnetic-precursor effect for this alloy.
