Abstract

The microwave surface impedance Z_s = R_s + iX_S and transmittivity T′_H of overdoped Tl₂Ba₂CuO_6+δ have been measured in a magnetic field up to 7 T in order to clarify the unusual temperature dependence of the DC resistivetransition field H* From the result of T′_H, columnar defects enhance H*, indicating that H* is the melting point of vortices instead of the mean field H_c2. The field dependence of R_s is found to be unusual as compared with that expected from the result of the DC resistivity.
