Query: Numerical Model for Calculating the Field Dependence of the Irreversible
  Magnetisation of Hard Ssuperconductors in High Pulsed Magnetic Fields   In type II hard superconductors the irreversible magnetization shows an
impressive variety of different magnetic field dependencies. In this paper we
will try to describe the M(H) relation at fixed temperature To by a numerical
model in which we incorporate two features: the magnetic and electric field
dependency of the local critical current density j(To,H,E). The electric field
is determined by the magnetic field sweep rate; in effect E ~ dB/dt. We
confront the model with experimental pulsed field magnetization measurements
(PFMM) on a fast melt processed YBa2Cu3O7 sample.
