  1. The temperature dependence of the magneto quantum oscillation amplitude (FFT amp.). The FFT amplitude temperature dependence is used to determine the effective mass of the superconducting quasi-particles. Magneto Quantum Oscillations in YBa2Cu4O8Gregory S. Boebinger, National High Magnetic Field Laboratory DMR 0654118Pulsed Field Facility User Program, Los Alamos National Laboratory Since the discovery of high temperature superconductors, clear magneto quantum oscillations have eluded researchers for nearly two decades. Experimental classification of these systems potentially holds the key to understanding the fundamental superconducting mechanism. Users of the NHMFL in collaboration with staff members were able to employ advanced contactless conductivity techniques to reveal for the first time the Fermi Surface cross sectional area of YBa2Cu4O8. Data are shown in the figure that show clear magneto quantum oscillations. Yelland, E.A.; Singleton, J.; Mielke, C.H.; Harrison, N.; Balakirev, F.F.; Dabrowski, B. and Cooper, J.R., Phys. Rev.

  2. Magneto Quantum Oscillations in YBa2Cu4O8Gregory S. Boebinger, National High Magnetic Field Laboratory DMR 0654118Pulsed Field Facility User Program, Los Alamos National Laboratory High temperature superconductors hold the promise to greatly reduce the energy footprint of the United States. Research at the NHMFL continues to make a significant impact on the experimental characterization of advanced materials. This type of detailed and exhaustive research effort requires cutting technologies and highly motivated teams of researchers. High magnetic field systems such as the 100T-MS magnet and the 45T hybrid magnet are essential tools for materials research. The NHMFL supports many of the world’s scientific experts in advanced instrumentation techniques and magnet system development and operation.
