V-doped YBa2Cu3O7-delta samples prepared under identical conditions ha
ve been investigated by magnetization measurements as a function of te
mperature and field. The critical current density, J(c), has been dedu
ced from the hysteresis data, using the appropriate field window withi
n which a linear relationship between Delta M(H) and J(c) is valid.
