An Active User Program

The DC Field Facility attracts hundreds of users a year. Here Yuanda Gao and Cory Dean conduct a transport experiment on graphene with a 35 tesla magnet.

Scientists using 35 tesla magnet

Located at MagLab headquarters near Florida State University in Tallahassee, the facility offers users the strongest, quietest, steady and slowly varying magnetic fields in the world, coupled with state-of-the-art instrumentation and experimental expertise.

The facility contains 14 resistive magnet cells connected to a 56 megawatt DC power supply and 15,000 square feet of cooling equipment to remove the heat generated by the magnets. The facility also includes several superconducting magnets operating at millikelvin temperatures. Among these instruments are several record holders, including the 45-tesla hybrid magnet, which offers scientists the strongest continuous magnetic field in the world. The research is supported by magnet plant and cryogenic system operators. Technicians design, build and repair instruments for user research. Scholar-scientists — world-class researchers with their own vibrant research interests — work directly with users to get the best measurements and data.

    Tunable Weyl Fermions in Chiral Tellurene in High Magnetic Fields

    Topology, screws, spin and hedgehogs are words not normally found in the same scientific article but with the discovery of Weyl fermions in thin tellurine films they actually belong together. The work in this highlight describes how Qui et. al. used the unique properties of tellurine and high magnetic fields to identify the existence of Weyl fermions in a semiconductor. This discovery opens a new window into the intriguing world to topological materials.
