Structure, microstructure and electrical properties of Tl-2212-silver composite / Faizah Md. Salleh and Ahmad Kamal Hayati Yahya

Superconductivity was discovered for the first time in 1911.'27J Dutch physicist at the University of Leiden, Kamerlingh Onnes acquired liquid helium at absolute temperature 4K by compressing helium gas. Using this liquid, he found that the electric resistance of Hg abruptly dropped near 4.2 K...
