(Hg, Mo)Sr 2Y 1− xCa xCu 2O 6+ δ. A new series of mercury-based high- Tc superconductor

A new series of Hg-based superconductor Hg 0.8Mo 0.2Sr 2Y 1− x Ca x Cu 2O 6+ δ with a maximum T conset of 98 K (at x = 0.65) as determined by electrical resistance measurements has been synthesized for the composition range 0.4 ⩽ x ⩽ 0.65. X-ray diffraction and electron diffraction both give the tet...

Summary:A new series of Hg-based superconductor Hg 0.8Mo 0.2Sr 2Y 1− x Ca x Cu 2O 6+ δ with a maximum T conset of 98 K (at x = 0.65) as determined by electrical resistance measurements has been synthesized for the composition range 0.4 ⩽ x ⩽ 0.65. X-ray diffraction and electron diffraction both give the tetragonal structure of 1212 cuprate with lattice parameters a = 3.825, c = 11.910 Å for x = 0.5 samples and a space group of P 4/mmm. Energy dispersive X-ray spectrometry analysis confirms that Hg and Mo are incorporated into the structure.
