Abstract

The purpose of this research is to explore superconductivity and superconductive material through the application of thin layers of superconductive material. Of particular interest is examination of the Meissner Effect.

To better understand the principles of superconductivity, an aerogel disk is placed in a very low pressure environment (approximately 10−4 Pascals) with a large potential difference applied between electrodes. One of the electrodes is a ceramic compound (barium yttrium copper oxide) which is then deposited onto the aerogel by way of cathodic arc evaporation. Cathodic arc evaporation is the process of passing an electric arc through a cathode, vaporizing the source, YBacCu3O7, which then condenses on the aerogel. Once the disk has a uniform density of the Yttrium and Barium, it is placed in liquid nitrogen to cool the disk to approximately 95 Kelvin.

The intended results of this research is to determine the resultant superconductivity of YBacCu3O7 coated aerogels.

In conclusion, this research is to examine the Meissner Effect when using a barium yttrium copper oxide coated aerogel made with a cathodic arc evaporation system. 4
