World-Record Electro-Magnet will enable new science of novel materials. PI: Greg Boebinger, National High Magnetic Field Laboratory Florida State University, University of Florida, Los Alamos National Laboratory NSF Award Number: DMR-0084173 and supported by DOE - Basic Energy Sciences The unusual shape of the magnetic field pulse from the new electro-magnet: a two second long pulse with a rapid race to peak field. The peak of the pulse is shown in the inset. The peak field will increase up to 100 Tesla as engineers learn how to best operate this new magnet behemoth. It was not until the 1950’s that scientists finally developed a detailed understanding of electron motions in even the simplest of metals, including gold, copper and aluminum. One key to our understanding relies on the fact that magnetic fields cause the electron motions to oscillate in specific patterns. These patterns unlock the role of electrons in creating many technologically- important properties of metals. Unlocking this same information from more complicated metals has been impossible without sufficiently powerful magnets. In 2006, the National High Magnetic Field Laboratory successfully commissioned a twelve-ton electro-magnet of a radically new design which generates a pulse of 85 Teslas, roughly two million times the Earth’s magnetic field. The magnet, promises to transform materials studies of complex metals, including magnetic metals, novel superconductors, and high-strength nano-scale alloys. For these materials, their very complexity requires the higher magnetic fields to reveal and sufficiently amplify the all-important electron oscillations.

Understanding Complex Metals using the new United States’ World-Record Electro-Magnet PI: Greg Boebinger, National High Magnetic Field Laboratory Funded by the National Science Foundation and the U.S. Department of Energy - Basic Energy Sciences The electron oscillations above are amplified by increasing the magnetic field. The new magnet will open the door for studies of many newly-developed metals.

Unlocking this same information from more complicated metals has been impossible without sufficiently powerful magnets. In 2006, the National High Magnetic Field Laboratory successfully commissioned a twelve-ton electro-magnet of a radically new design. A pulse of electrical current through the magnet generates 85 Teslas, roughly two million times the Earth’s magnetic field. This United States’ magnet, which resulted from a decade-long collaboration of the NSF and DOE, promises to transform materials studies of complex metals, including magnetic metals, novel superconductors, and high-strength nano-scale alloys. For these materials, their very complexity requires the higher magnetic fields to reveal and sufficiently amplify the all-important electron oscillations.
