Researchers believe they have unlocked the mystery to what makes high-temperature superconductors tick. According to a team from Oak Ridge National Laboratory and the University of Tennessee, the reason these materials superconduct at such high temperatures may be a magnetic resonance that causes their anti-ferromagnetic lattice to oscillate opposing-spin orientations in synchronization with the opposing-spin orientations of the so-called Cooper pairs passing through the superconductor's molecular lattice. Magnetic-resonance excitation is believed to be the mechanism that generates Cooper electron pairs in high-critical-temperature superconductors. Recent experiments at the National Institute of Standards and Technology have confirmed the theory in the superconductor called praseodymium lanthanum cerium copper oxide. The Oak Ridge-UT team also reported a universal law governing all high-temperature materials--their magnetic-resonance energy is proportional to their superconductivity transition temperature. If the researchers are correct that magnetic resonance serves the same function as phonon lattice vibrations in low-temperature superconductors, then room-temperature superconductors could be on the horizon.
