The role of a transport current on the annihilation of the surface barrier for a high‐temperature type‐II superconducting infinite slab of arbitrary thickness as well as for a high‐temperature type‐II superconducting cylinder are investigated. The London penetrating field, the vortex fields, and the Gibbs potential are calculated. The barrier depends on the external field strength, the value of the transport current flowing through the sample, and the orientation of the external field. Agreement with previous results in some cases is found.
