Abstract Since the discovery of iron-based superconductors, a new chapter has been opened in the history of the development of high temperature superconductivity. In the past decade, there have been remarkable achievements in the theory, experiments, and applications of iron-based superconductors, and our understanding of the mechanism of superconductivity has been deeply enriched. Here, we review the research progress on high-pressure studies on the superconductivity, flux pinning, and vortex dynamics of iron-based superconductor families. The topics include pressure-induced superconductivit...

MIT researchers and colleagues have turned a “magic” material of atomically thin graphene into three useful electronic devices. All are key to the quantum electronics industry.

Date Time Standing Out: Unusual Magnetic Transition in Perovskite Oxide Can Help Boost Spintronics Transition metal perovskites oxides exhibit several desirable properties, including high-temperature superconductivity and electrocatalysis. Now, scientists at Tokyo Institute of Technology explore the structure and properties of a perovskite oxide, PbFeO 3, in anticipation of the unusual charge distribution and exotic magnetic transitions displayed by such systems. They report two of the magnetic transitions, with a distinctive transition above room temperature and look into its causes, opening...

Date Time Share SLAC It’s an example of how surprising properties can spontaneously emerge in complex materials – a phenomenon scientists hope to harness for novel technologies. Creating a two-dimensional material, just a few atoms thick, is often an arduous process requiring sophisticated equipment. So scientists were surprised to see 2D puddles emerge inside a three-dimensional superconductor – a material that allows electrons to travel with 100% efficiency and zero resistance – with no prompting. Within those puddles, superconducting electrons acted as if they were confined inside...

Date Time U.S. Magnet Development Project for CERN Particle Collider Upgrade Moves Forward The High-Luminosity Large Hadron Collider (HL-LHC) Accelerator Upgrade Project magnets use conductors made of niobium-tin to generate a stronger magnetic field compared to predecessor technology. These world-record-setting magnets will have their debut in the HL-LHC project at CERN. Its run will be the first time that U.S.-built niobium-tin magnets will be used in a particle accelerator for particle physics research.
