Discovery and Research of High Tc Superconductor in the Institute of Physics, Academia Sinica

1. Introduction The discovery of possible high T_C super-conductivity at 35K in La-Ba-Cu-O systemsparked an intense study on the new classof cupric oxides by a few laboratoriesincluding the joint research group of highT_C superconductivity in the Institute ofPhysics, Academia Sinica. A few monthslater we not only confirmed the
