The critical current density is an important factor as well as the critical temperature and the critical magnetic field in power application of superconductors. A magnitude of the critical current density is determined by flux pinning interactions. In this report the flux pinning phenomenon is briefly explained and it is discussed what is to be done for the purpose of increasing the critical current density. Measuring methods of the critical current density are also reviewed.
