| 中文摘要 | We have carried out magnetic measurements and transmission electron microscopy (TEM) study on over-doped Tl2Ba2CuO6+delta (Tl-2201) single crystal samples with a range of different oxygen content. Magnetic measurements show the existence of an irreversibility line that is considerably lower than the upper critical field B-c2 and displays a positive upward curvature. We propose that the critical field determined from magnetoresistive transitions for strongly over-doped sample is not the true upper critical field but the irreversibility field instead. TEM study has shown that phase separation due to oxygen inhomogeneity is presented in the strongly overdoped samples that have very low T-c value and exhibit unusual temperature dependence of the upper critical field. |
