Source:DOE/SLAC National Accelerator LaboratoryA new study shows that nickel oxide superconductors, which conduct electricity with no loss at higher temperatures than conventional superconductors do, contain a type of quantum matter called charge density waves, or CDWs, that can accompany superconductivity.The presence of CDWs shows that these recently discovered materials, also known as nickelates, are capable of forming correlated states -- 'electron soups' that can host a variety of quantum phases, including superconductivity, researchers from the Department of Energy's SLAC Nat...

source：azoopticsPulsed lasers, a crucial component of the laser industry, are continuously developed to produce higher repetition frequencies and greater intensity. Recently published research findings from the Shanghai Institute of Optics and Fine Mechanics at the Chinese Academy of Sciences exhibit a crystal with promising pulsed laser properties. Research efforts led by the group of Professor Yin Hang and published in Optics & Laser Technology have demonstrated the first laser operation of perovskite oxide LaAlO3 doped with 0.1 at% Nd ions and 0.2 at% Th (Nd,Th:LaAlO3).What are Pulsed L...

source:natureAbstractThe current work is mainly devoted to the synthesis, structural, electrical, and magnetic characterization of Sr1−XLaXFe12O19 (X = 0.2–0.8) (SLFO) nanoparticles synthesized via the hydrothermal technique. The hexagonal peaks were determined using X-ray diffraction analysis. The obtained results indicated that the lattice constants were noted to be increasing from 0.58801 to 0.58825 nm (a = b), and 2.30309 to 2.30341 nm (c) with increase of in ‘X’. The morphological studies ensured that the grains as well as nanoparticles of SLFO acquired almost spherical shape. The optical...
