Pseudogaps Are Not The Answer: The Continuing Mystery of High-Temperature Superconductivity. Photo: Because superconductivity repels a magnetic field, this permanent magnet levitates above a cuprate high-temperature superconductor. Scientists were surprised to find the same pseudogap energy signature in both high-Tc cuprates and ferromagnetic manganites.
Stanford University physicist Zhi-Xun Shen, a leader in the study of high-Tc superconductivity, says, “I think our findings will add fire to the debate over one of the great scientific mysteries of our time: what is behind the phenomenon of high-Tc superconductivity? Are many of the anomalous properties we see in the cuprates manifestations of high-Tc superconductivity and CMR? What is the underlying physics ingredient that gives rise to these two competing sibling states? These are important questions that future experiments will try to answer.”
