History

Historical Context

In 1986, physicists Georg Bednorz and K. Alex Müller discovered high-temperature superconductivity in lanthanum barium copper oxide, achieving a critical temperature of 35 K. This breakthrough, which surpassed the previous record of 23 K, spurred over $100 million in research funding from the National Science Foundation, leading to ongoing studies on materials like La3Ni2O7 that could revolutionize energy transmission and storage.
