Using a special technique performed in the MagLab's high fields, researchers have uncovered a method to understand spin ice materials.

Generally, light transmission is symmetrical - it's the same if you shine a light through a material forward or backwards. Using powerful pulsed fields, researchers revealed one-way transparency in a nickel-tellurium-oxygen based material showing that light flows one way across the telecom range – a finding that opens the door to exciting new photonics applications.

Theory predicted that the transition between the superconducting and superfluid regimes should be continuous for electrons and holes in solid materials, but recent high magnetic field experiments performed by researchers from Columbia, Harvard and Brown Universities demonstrated the crossover between coupling regimes.

High-magnetic-field, high-frequency electron paramagnetic resonance demonstrates how coordination chemistry can be leveraged to stabilize a desired electronic/magnetic state in an organic molecule. In this experiment, the long-sought magnetic (triplet) ground state in a benzene ring is stabilized by a pair of metal ions above and below the six-carbon ring.

A new class of correlated quasiparticle states discovered in a multi-valley semiconductor using optical absorption measurements in pulsed magnetic fields. This new type of multi-particle state results when excitons interact simultaneously with multiple electron reservoirs that are quantum-mechanically distinguishable by virtue of having different spin and/or valley quantum numbers.

Scientists have used high-field nuclear magnetic resonance (NMR) to reveal how fungal pathogens use carbohydrates and proteins to build their cell walls (the protective layers outside of the cell). These findings will guide the development of novel antifungal drugs that target the cell wall molecules to combat life-threatening diseases caused by invasive fungal infections.

Using X-ray diffraction, scientists can now detect atoms themselves moving further apart or closer together in high magnetic fields, giving science a crystal clear view of nature.

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.

 

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.

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.
