Synthesis and ac susceptibility of YCa 2Cu 3O 7− δ

The bulk superconducting YCa 2Cu 3O 7− δ compounds are prepared at an ordinary pressure of oxygen by conventional solid-state reaction method. The formation of sample is tested by means of XRD and is studied for their ac susceptibility below room temperature up to 77.5 K. The samples are found singl...

Description
Summary:	The bulk superconducting YCa 2Cu 3O 7− δ compounds are prepared at an ordinary pressure of oxygen by conventional solid-state reaction method. The formation of sample is tested by means of XRD and is studied for their ac susceptibility below room temperature up to 77.5 K. The samples are found single-phase orthorhombic structure and found superconducting at 83.5 K. It is shown that the analysis is consistent with published data on YBa 2Cu 3O 7− δ oxide superconductor.
