The high-temperature superconduct?or, HgBa 2 CuO 4؉ ( '0), is the 5rst and arguably the most simple member of the homologous series of mercury-based cuprates, of general formula HgBa 2 Ca n؊1 Cu n O 2n؉2؉ (n ؍ 1. . . 8). The presence of interstitial oxygen in the HgO rock salt layer is crucial in
We have studied as-synthesized, vacuum-annealed and high-pressure oxygen annealed HgBa2CuO4+6 (Hg-1201 ) using Raman scattering. The apical-oxygen vibrational frequencies showed a slight but systematic shift (590, 591 and 587 era-t ), in agreement with the slight change in the Hg--O bond length from
