抄録

We prepared (Hg_0.7Tl_0.3)₂Ba₂(Y _0.8Ca_0.2)Cu₂O_8-δ with a T_c of 65 K at 5 GPa and 1050 °C and analyzed its structure by neutron powder diffraction. Rietveld analysis showed highly disordered atomic arrangements on double (Hg,Tl)O layers, the absence of oxygen vacancies, and an underdoped state of the CuO₂ sheet.
