Material Specification for Hg:121; [Hg-Ba-Cu-O]
Process: Solid State Reaction
Notes: The authors cite S.N. Putilin et al., Physica C, Vol. 212, 266 (1993), and summarize the procedure as follows. "All samples of Hg 1:2:(m-1):m examined here were synthesized and studied previously. ... Structure characterization was carried out with a Rigaku D-MAX/BIII powder diffractometer. ... The x-ray data revealed that these samples have a phase purity of about 80% for Hg 1:2:2:3, 90% for Hg 1:2:1:2, and ≥95% for Hg 1:2:0:1."

"We have therefore examined resistively the T

The QHP environment up to 45 GPa was provided by a helium membrane, diamond anvil cell (DAC) with a stainless steel gasket. Samples of sizes (of about) 300x300x25 µm
3 were loaded into the hole in the gasket with MgO as the pressure medium. The pressure was generated by a diaphragm press at the desired temperatures and kept constant during the measurements. Pressure was determined with an uncertainty of ±5% at several temperatures by the temperature-corrected ruby florescence method on several (approximately) 3 µm sized ruby cystals spread across the sample. QHP up to (about) 18 GPa was generated by a modified WC anvil clamp using a pyrophyllite gasket with two steatite disks as a pressure medium. Samples of size (about) 800 µm diameter x 50 µm were used. The pressure was changed only at room temperature and determined with an overall uncertainty of ±15% by converting the applied load at room temperature which was calibrated against a Pb manometer. The temperature was measured by a chromel-alumel thermocouple or a diode thermometer, which was situated closely to the sample with an uncertainty of ±0.1 K. The superconducting transition was determined resistively by the standard four-lead technique in the WC anvil or by a pseudo four-lead technique in the DAC. A pseudo four-lead resistance measurement was made by pressing two tungsten leads onto the sample. Insulation from the gasket was achieved by a thin layer of 0.3 µm Al
