In this work we measured high-Tc superconducting Bi2Sr2CaCu2O8+δ (BSCCO) samples with periodic surface holes created by a focused ion beam using differential magneto-optics with field modulation. We found that the dynamic irreversibility line of the patterned regions is shifted …

In this work we studied the B–T phase diagram of vortex matter in high-Tc and low-T c type II superconductors. First and second order phase transitions of vortex matter in the layered high-Tc superconductor Bi2Sr2CaCu2O8 were mapped using local magnetization measurements with mi…
