Weinvestigate the crossover temperature T^* as a function of dopingin (Ca_xLa_1−x)(Ba_1.75−xLa_0.25+x)Cu₃O_y, where the maximum T_c (T cmax ) varies continuously by30% between families (x) with minimal structural changes. T^* isdetermined by dc-susceptibility measurements. We find that T^* scales withthe maximum Néel temperature T Nmax of each family. This resultstrongly supports a magnetic origin of T^* and indicates thatthree dimensional interactions play a role in its magnitude.
