Novel metallofullerene boosts dynamic nuclear polarization

In this study, researchers added a low concentration of the endohedral metallofullerene (EMF) Gd2@C79N to DNP samples, finding that 1H and 13C enhancements increased by 40% and 50%, respectively, at 5 teslas and 1.2 Kelvin.

Ceramic insulation for high-temperature superconducting wire

MagLab scientists and engineers have developed a special coating on Bi-2212 superconducting wire for electrical insulation in superconducting magnets that will enable the wire to be used in ultra-high field nuclear magnetic resonance magnets.

Switchable transmission of quantum Hall edge states in bilayer graphene

In the 14 years since its discovery, graphene has amazed scientists around the world with both the ground-breaking physics and technological potential it displays. Recently, scientists from Penn State University added to graphene's gallery of impressive scientific achievements and constructed a map that will aid future exploration of this material. This work is emblematic of the large number of university-based materials research efforts that use the MagLab to explore the frontiers of science.

Exciton states in a new monolayer semiconductor

Analogous to the unique spectral fingerprint of any atom or molecule, researchers have measured the spectrum of optical excitations in monolayer tungsten diselenide (WSe2), which is a member of a new family of ultrathin semiconductors that are just one atomic layer thick.

2D electron-hole "superconductor": Topological excitonic insulator

Decades ago a mechanism was proposed that described a quantum phase transition to an insulating ground state from a semi-metal (excitonic insulator, or EI) using very similar mechanics to those found in the BCS description of superconductivity. The discovery of this transition to an EI in InAs/GaSb quantum wells is striking not only for the long-sought experimental realization of important physics, but also the presence of recently proposed topological behavior.

Tweaked recipe delivers record current-carrying capacity in Bi-2212 wires

MagLab-industry partnership ups the critical current density of this high-temperature superconductor by a third.

Dynamics of helium-3 in nanotubes

Experiment shows that emergent quantum fluid behavior of helium-3 confined to one dimension is observable using special low-temperature NMR techniques.

New magnetic topological semimetal has energy-saving potential

Researchers discover that Sr1-yMn1-zSb2 (y,z < 0.1) is a so-called Weyl material that holds great promise for building devices that require far less power.

High-temperature superconducting coils tested for future NMR magnet

Bi-2223 shows promise for 30-tesla all-superconducting instrument for nuclear magnetic resonance.
