Two researchers play with nanostructures in a fun, fertile physics playground: the space between two things.
The work by Dagan et. al. explores the emergence and coexistence of superconductivity and magnetism at the interface between insulating, non-magnetic LaAlO3 and SrTiO3 nanowires at low temperatures. The effect of the antiparallel magnetic order on the resistance of the 50 nm wide patterned wires follows the form of giant magnetoresistance (GMR) at low applied magnetic fields.
Looking for ways to make better superconductors for the next-generation particle accelerators, a young scientist homed in on how they were heat-treated. He was getting warmer.
Scientists of the NHMFL-PFF have employed Resonant Ultrasound Spectroscopy to reveal a thermodynamic signature of the “Pseudo-Gap” within and beyond the superconducting phase boundary of YBCO. This experiment provides thermodynamic evidence that the pseudo gap is connected to the superconducting ground state in the cuprate materials.
The finding in fullerides opens a new way of exploring the role electron interactions play in high-temperature superconductivity
Niobium diselenide is found to retain its superconductivity even under very high magnetic fields.
Research on La2-xSrxCuO4 provides a new perspective on the mechanism for the superconductor-insulator transition in cuprates, one of the key questions in condensed matter physics.
Hop on this information train for a step-by-step look at how one physicist uses magnets to understand superconductors, spin liquids and why some materials get frustrated.
A lot of the research conducted in powerful magnets ends up having a powerful effect on our day-to-day lives.
At the National MagLab and other labs across the globe, the race to discover ever-warmer superconductors is heating up. Find out what these materials are, what they’re good for and why this field is red hot.
