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.


Our magnets are open to all scientists — for free — via a competitive process and we accept proposals throughout the year.

    Quantum Hall Effect in a Three-Dimensional Topological Insulator

    The work by Chen et. al. explores the quantum hall effect (QHE) that develops in BiSbTeSe2 at low temperatures and high magnetic fields. BiSbTeSe2 is a topological insulator, meaning it is a bulk insulating material that at low temperatures develops a quantum mechanical state that allows conduction of electrons at the surface similar to a metal. The observation of the QHE in BiSbTeSe2 is further confirmation of the theory governing these unique materials.
