Abstract
We have measured the surface resistance and transmittivity of overdoped TlB a2CuO6+delta in magnetic field up to 7 T in order to investigate the unusua l de resistive transition, introduction of columnar defects largely shifts the irreversibility line to higher field, showing that the resistive transi tion is caused by the melting of the vortex lattice. It is found that flux flow resistance of this compound is unusual as compared with that expected from the dc resistivity. PACS numbers: 74.72.Fq, 74.25.Fy, 74.25.Nf.
