Join us at Science Night on Jan 20 as we share our enthusiasm for magnets and the science they enable at this free, family-friendly virtual event.
New high-field Hall data may hold clues that explain unconventional superconductivity.
Scientists use our magnets to explore semiconductors, superconductors, newly-grown crystals, buckyballs and materials from the natural world — research that reveals the secret workings of materials and empowers us to develop new technologies.
Scientists here are working to optimize petroleum refining, advance potential bio-fuels such as pine needles and algae, and fundamentally change the way we store and deliver energy by developing better batteries.

Clues About Unconventional Superconductivity From High-Field Hall Data
13 December 2021
In everyday life, phase transitions - like when water boils and turns into steam or freezes and becomes ice - are caused by changes in temperature. Here, very high magnetic fields are used to reveal a quantum phase transition not caused by temperature, but instead driven by quantum mechanics upon changing the concentration of electrons, work that could hold critical clues that explain high-temperature superconductivity.
Novel "hot-bronze" Nb3Sn for compact accelerators
22 November 2021
A new "hot bronze" thin film growth recipe was developed to produce high quality superconducting Niobium-Tin (Nb3Sn) films that are easier to fabricate and that outperform existing technologies.
New quantum tricks in nitride materials
22 November 2021
Gallium nitride (GaN) and Niobium nitride (NbN) are widely used in today's technologies: GaN is used to make blue LEDs and high-frequency transistors while NbN is used to make infrared light detectors. This experiment explores whether a nitride-based device may be relevant for quantum technologies of the future.
