| Abstract: | The nominal (Hg1-xRex)Sr2CuO4+delta (x = 0.10 and 0.20) samples were synthesized at similar to 920degreesC in partial vacuum. The compound with x = 0.10 exhibits superconductivity at similar to 54 K while the composition x = 0.20 is non-superconducting down to 5 K. On cooling below 10 K in an applied field of 4 kOe, the former causes a noticeable upturn in the field cooled (FC) magnetization signal. Such a change in magnetic response is also reflected in the magnetic hysteresis loop generated at 9 K. We attribute this effect to a paramagnetic contribution arising from Re in (Hg,Re)-1201 phase. |
