Abstract


Through our research, we’ve gained a deeper understanding of cuprate materials, which are loosely defined as materials containing anionic copper complexes. Cuprates are known for their high-temperature superconductivity. In this project, we focused on a Fe-LSCO Sr 0.16 Sample. To test the resistance of the sample, we attach voltage and current contacts with the help of a Silver Paste. After the contacts are secured on the sample, we place it in extreme low-temperature cryogenic tanks, which can be described as large thermoses with liquid helium or liquid nitrogen inside to keep it cool. The sample is placed in the tank with a probe and its resistance is measured through a resistance bridge. The results show a point of zero resistance when the sample reaches a certain temperature; this is when it becomes superconductive.
