摘要
A significant effect of sample thickness on three components of the magnetic flux density distribution on square-shaped superconductor surface is shown,and the critical current density jc of the superconductor from the fully penetrated field μ_(0)H^(*) observed in magneto-optic imaging experiment is calculated.
