Spintronics technology has taken a step forward with new experimental evidence of parallel spin-momentum locking in chiral materials. Results from the spin branch of the Bloch experiment station contributed to the discovery.
A unifying theory of superconductivity: Finding common symmetry
A global goal of physics is greater knowledge of the mechanism of superconductivity. A research group from China and the United Kingdom recently reported in Nature Physics the pairing symmetry of iron-based superconductor KFe2As2, which contains only hole pockets on the fermi surface. The result, which includes measurements at BLOCH beamline, brings science closer to a unified theory of unconventional superconductivity for iron-based materials.
To glue and be glued – unusual electron pairing gives clue to high-temperature superconductivity
A team of researchers have studied the high-temperature superconducting cuprate-material Nd1.85Ce0.15CuO4 with a small amount of electron-rich atoms added, a practice called electron-doping. The material turns out to have unusual electronic properties underpinning its superconductivity. The result has important implications for a larger group of similar superconducting materials.
Honeycomb silicon carbide: a research surprise
While physicists and materials scientists have been trying to produce large-area, two-dimensional, high-quality silicon carbide (SiC) for some time with little to no success, a recent study at Bloch beamline made an unexpected breakthrough.
