Using LabVIEW to Study High-Temperature Superconductors
JURPA 2025 Cover.
This study investigated the critical temperature of the high-temperature superconductor YBa2Cu3O7 using an experimental setup designed to measure temperature, voltage, and current. The setup included a four-point probe, LabVIEW programming for data acquisition, and liquid nitrogen for cooling. Resistance versus temperature data was collected as the sample warmed, revealing evidence of superconductivity. The critical temperature was determined using two methods: the temperature at which resistance became zero, determined as 90.4 K, and an extrapolated linear fit method, determined as 100.0 K. The two values deviated from the accepted critical temperature of 93 K. Future improvements are proposed to enhance the reliability of the results. Despite discrepancies, the experiment successfully demonstrated superconducting behavior in YBa2Cu3O7.
