These monthly highlights, selected by MagLab Director Greg Boebinger, represent the most promising and cutting-edge research underway in the lab’s seven user facilities.
The findings contribute to scientists' understanding of magnetic materials that could point the way to future applications.
MagLab users have modified the critical current of Nb3SN, a material that was thought to be fully exploited, and boosted its performance by 50%.
The observation of topological states coupled with superconductivity represents an opportunity for scientists to manipulate nontrivial superconducting states via the spin-orbit interaction. While superconductivity has been extensively studied since its discovery in 1910, the advent of topological materials gives scientists a new avenue to explore quantum matter. BiPd is being studied using "MagLab-sized fields" by scientists from LSU in an effort to determine if it is indeed a topological superconductor.
Pulsed magnets are designed to operate near their structural limits to be able to generate extremely high magnetic fields. The coils have a limited life expectancy and thus need to be replaced on occasion. Fabrication of these large coils are now being done at the MagLab where advanced nondestructive examinations can be performed. Because of more rigorous quality controls and improvements in high-strength conductors and reinforcement materials, the lifetime of these coils can be extended.
With advanced techniques and world-record magnetic fields, researchers have detected new MRI signals from brain tumors.
Combining high-field NMR with infrared microscopy, scientists learned more about how gas diffuses in a novel class of molecular sieves that could one day be used for gas separation.
Scientists will be able to apply the technique to characterize similar molecules, helping develop vaccines and drugs to treat bacterial infection.
Scientists revealed previously unobserved and unexpected FQH states in monolayer graphene that raise new questions regarding the interaction between electrons in these states.
Insights into the structure and movement of T cell surface proteins could lead to new ways to fight cancers, infections and other diseases.
With unprecedented sensitivity and resolution from state-of-the-art magnets, scientists have identified for the first time the cell wall structure of one of the most prevalent and deadly fungi.
Scientists have long pursued the goal of superconductivity at room temperature. This work opens a route towards one day stabilizing superconductivity at room temperature, which could open tremendous technological opportunities.
Researchers have discovered a new method to create encapsulated carbon nanomaterials that contain fluorine. Known as fullerenes, these nanocages are promising candidates for clean energy applications.
Scientists found that the emergence of an exotic quantum mechanical phase in Ce1-xNdxCoIn5 is due to a shape change in the Fermi surface. This finding ran counter to theoretical arguments and has led investigators in new directions.
Weyl metals such as tantalum arsenide (TaAs) are predicted to have novel properties arising from a chirality of their electron spins. Scientists induced an imbalance between the left- and right-handed spin states, resulting in a topologically protected current. This was the first time this phenomenon, known as the chiral anomaly, has been observed.
This research established experimental evidence for the long sought-after transition of a small, two-dimensional sheet of electrons to a solid state.
This work investigates a series of oxoiron complexes that serve as models towards understanding the mechanism of catalysis for certain iron-containing enzymes.
Molecular fossils of chlorophyll (called porphyrins) more than 1.1 billion years old find suggest that photosynthesis began 600 million years earlier than previously established.
A new pH sensitive contrast agent for MR imaging has been developed that produces image contrast based on the local pH and that has great potential for use in living animals and medical diagnostics.
The causes of migraines are not well understood, with treatment limited to addressing pain rather than its origin. Research conducted with hydrogen MRI is attempting to identify the "migraine generator."
This work provides important insight into one of the parent materials of iron-based superconductors.
