Introduction 1.1 Background of study Superconductivity is a phenomenon where the electrical current can conduct electricity with a zero resistance. Since discovered in 1911 by Dutch physicist Heike Kamerlingh, superconductor material has been used widely in many applications.

This followed by discovery of yttrium barium copper oxide (YBa2CuO7) in 1987 by Muller and Bednorz. This YBa2CuO7 received a great intention from many researchers. 1.2 Problem statement Theoretically, YBa2CuO7 is one of the ceramic superconductor that has an excellent ability Brittleness and low critical current have been a problem to the ceramic samples. 1.3 Objective The objectives of this study are: To study the magnetic, electrical and microstructural properties of YBA2CuO7To compare the sol-gel method, co-precipitated method and solid-state method that is used to prepare the YBA2CuO7 1.4 Significant of study The result of this study is to present a properties of YBA2CuO7 using different method. The sol-gel processing routes produce small distribution of the grain size and show highly pure homogeneity of composition in the YBA2CuO7 samples give a better performance of YBA2CuO7 in 2.0 Literature review 2.1 Superconductivity Since the discovery of the high temperature superconductor (HTS), extensive studies have been carried out in order to develop these materials for applications.
