Superconductivity is a remarkable quantum phenomenon characterized by zero electrical resistance and perfect diamagnetism, known as the Meissner effect. Since the discovery of high-temperature superconductivity (HTS) in copper-oxide ceramics (cuprates) in 1986, researchers have struggled to understand the mechanisms behind superconductivity at temperatures far exceeding those predicted by the conventional Bardeen–Cooper–Schrieffer (BCS) theory. This paper explores the fundamental principles of superconductivity, focusing on the phenomena of superdiamagnetism and the mechanisms proposed for high-temperature superconductivity. It also reviews major experimental findings and theoretical models, and discusses the current challenges and future directions of research aimed at achieving room-temperature superconductivity.
