The maximum value [Delta] of the negative Hall resistivity [rho][sub [ital xy]] of Y[sub 1[minus][ital x]]Pr[sub [ital x]]Ba[sub 2]Cu[sub 3]O[sub 7[minus][delta]] (0[le][ital x][approx lt]0.13) and YBa[sub 2]Cu[sub 3]O[sub [ital y]] (6.73[approx lt][ital y][le]6.84) single crystals scales with [ital T]/[ital T][sub [ital c]], exhibiting a maximum [Delta][sub max] for [ital T]/[ital T][sub [ital c]][approx]0.96 and vanishing for [ital T]/[ital T][sub [ital c]][approx lt]0.87. [Delta][sub max] scales with [ital T][sub [ital c]] and decreases monotonically with decreasing [ital T][sub [ital c]] to zero for [ital T][sub [ital c]][approx lt]70 K. The Hall conductivity [sigma][sub [ital xy]] vs [ital B] data have been analyzed using the expression [sigma][sub [ital xy]]=[ital C][sub 1]/[ital B]+[ital C][sub 2][ital B], where the two terms are associated with motion of the magnetic vortices and the quasiparticles in the vortex cores, respectively, yielding [ital C][sub 1] and [ital C][sub 2] as functions of [ital x], [ital y], and [ital T].
