The Crystallines and Transport Properties of Manganites with High Temperature Coefficient of Resistance
碩士 === 大葉大學 === 電機工程學系碩士班 === 94 === In this article, We will study the effects of different doping on the temperature coefficient of restistance(TCR), metal-insulator transiyion temperature(TP) of La-Ca-Ba-Sr-MnO3 sample. We found that the Maximun of TCR was decreased when TP was increased. We also...
