Single-step synthesis and crystal structure of HgBa2CuO4+delta with a T-c of 97 K

Abstract:

Single-phase samples of HgBa2CuO4+δ (Hg-1201) have been synthesised from a reaction between a pre-synthesised precursor Ba2CuO3 and HgO, using a rapid-heat rapid-cool technique. This method yields high-quality samples with (as-synthesised) superconducting transition temperatures, Tc up to 97 K, as defined by the onset of diamagnetism. The phase purity and crystal structure were identified by powder X-ray diffraction. In addition, powder neutron diffraction was employed to elucidate the struct...
