Scientists at the Pulsed Field Facility recently found that applying an intense magnetic field to the mineral atacamite (a "frustrated" quantum magnet) yields unusual behavior associated with a novel state of matter known as quantum spin liquid.
This highlight focuses on the development of new thermometry required to study quantum materials and phenomena in high magnetic fields and at ultralow temperatures. The team has demonstrated that exceedingly small quartz tuning forks bathed in liquid 3He maintain a constant calibration that is magnetic field independent, thereby opening the use of these devices as new sensors of the response of quantum systems.
High-resolution electron magnetic resonance studies of the spin-wave spectrum in the high-field phase of the multiferroic Bismuth ferrite (BiFeO3) reveal direct evidence for the magnetoelastic coupling through a change in lattice symmetry from rhombohedral to monoclinic. This study provides important information for designing future spintronics devices based on BiFeO3.
This highlight reports on the still poorly understood transition to an electron crystalline state (the Wigner crystal) in a two-dimensional system at extremely low densities, observable at low temperatures as a function of magnetic field. This experiment finds a surprising stabilization of the Wigner crystal arising from magnetic-field-induced spin alignment. Such electrically-delicate samples require the ultra-low-noise environment and experimental techniques available at the High B/T facility.
This work reports the first observation of the dynamical generation of a spin polarized current from an antiferromagnetic material into an adjacent non-magnetic material and its subsequent conversion into electrical signals
A new experimental technique allowed physicists to precisely probe the electron spins of an intriguing compound and uncover unexpected behavior.
Magnetic resonance (MR) signals of sodium and potassium nuclei during ion binding are attracting increased attention as a potential biomarker of in vivo cell energy metabolism. This new analytical tool helps describe and visualize the results of MR experiments in the presence of in vivo ion binding.
