We have observed vortices of the high-temperature superconductor using the Bitter technique. Hopping movement of vortices of Y-123 and Bi-2212 single crystal was observed in the temperature range of 50-90 K (Tc) by the thermal energy. We estimated pinning potential by migration length. The pinning potential, we have also observed the vortex pattern of Y-123 QMG sample including Y-211 phase. We found that vortex existed in the grain boundary of Y-211 and Y-123 phase.
