Scientists using MagLab magnets bolster theory that quantum fluctuations drive strange electronic phenomena.
High magnetic fields reveal the electronic interactions underlying high-temperature superconductivity in the iron pnictides. This research unifies the superconducting phase diagram of the pnictides with those of other quantum critical, high-temperature superconductors, such at the cuprates.
The Pulsed Field Facility's 240-ton generator is so massive and so powerful that it can't sit on the ground.
Comprehensive angle-resolved quantum oscillation measurements on YBa2Cu3O6+x in magnetic fields approaching 100 tesla are used to address longstanding problem of the normal state electronic of underdoped high temperature superconducting cuprates. The symmetry of the Fermi surface points uniquely to its reconstruction by biaxial ordering of the charge and bond degrees of freedom.
Scientists working at the MagLab have made a breakthrough in identifying the state from which high-Tc superconductivity emerges. Their results are in the June 19th issue of the journal Nature.
The high-magnetic field phase diagram to 65 Tesla of the MV2O4 family (M = Cd, Mg) reveals new multiferroic phase transitions that point to an unusual interplay between spin-orbit interactions and frustrated magnetism.
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.
Using optical spectroscopy and the MagLab’s unique 60 tesla long-pulse magnet in Los Alamos, scientists have shown how nitrogen dopant atoms in gallium arsenide (GaAs) can form extended “supercluster” states or can break up into localized nitrogen clusters. Nitrogen-doped GaAs (GaAs1-xNx) is a semiconductor alloy with potential applications for a wide range of energy-related applications such as photovoltaics.
Multiferroics — “Spintronics without heat” — coupled ferromagnetism and ferroelectricity can provide a new class of functional materials for needed applications including magnetic sensing, data storage and manipulation, high–frequency and high–power electronics, and energy savings.
