Yg. Xiao et al., SCALING BEHAVIOR OF MAGNETIC HYSTERESIS LOOPS AND CRITICAL-CURRENT DENSITY IN MELT-TEXTURED (Y1-XPRX)BA2CU3O7-DELTA, Physica. C, Superconductivity, 282, 1997, pp. 2309-2310
Magnetization measurements are performed on MTG (Y1-xPrx)Ba2Cu3O7-delt
a samples with x=0 and 0.08. The magnetic hysteresis loops and related
critical current densities for different temperatures are found to ex
hibit scaling behavior when H, M and J(c) are normalized corresponding
ly. It is shown that this behavior can be described qualitatively well
for low scaled field (h) region based on an extended critical-state m
odel. Also, Pr doping is found not to affect the scaling behavior itse
lf in the investigated level.
