GB/T 17711-1999 "DC resistance test method for the critical temperature Tc of yttrium barium copper oxide (123 phase) superconducting thin films" stipulates the critical temperature measurement method of yttrium barium copper oxide superconducting thin films. The standard specifies the test principle, specifies the requirements for sample preparation and equipment, describes the process and operation points of determining the critical temperature Tc by measuring the DC resistance with temperature changes, and also provides data processing and error analysis methods, providing a unified technical standard for the scientific and accurate determination of the critical temperature of the superconducting thin film, and assisting the performance evaluation and research of superconducting materials.
