An international team of researchers has discovered the hydrogen atoms in a metal hydride material are much more tightly spaced than had been predicted for decades-a feature that could possibly facilitate superconductivity at or near room temperature and pressure. [21] That's why physicists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory studying a well-known cuprate containing layers made of bismuth oxide, strontium oxide, calcium, and copper oxide (BSCCO) decided to focus on the less complicated "overdoped" side, doping the material so much so that superconductivity eventually disappears. [20] Scientists at the U.S. Department of Energy's Ames Laboratory have developed a method to accurately measure the "exact edge" or onset at which a magnetic field enters a superconducting material. [19] TU Wien has now made a major advance towards achieving this goal and, at the same time, has furthered an understanding of why conventional materials only become superconducting at around-200°C [18] The emerging field of spintronics leverages electron spin and magnetization. [17] The first known superconductor in which spin-3/2 quasiparticles form Cooper pairs has been created by physicists in the US and New Zealand. [16] Now a team of researchers from the University of Maryland (UMD) Department of Physics together with collaborators has seen exotic superconductivity that relies on highly unusual electron interactions. [15] A group of researchers from institutions in Korea and the United States has determined how to employ a type of electron microscopy to cause regions within an iron-based superconductor to flip between superconducting and non-superconducting states. [14] In new research, scientists at the University of Minnesota used a first-of-its-kind device to demonstrate a way to control the direction of the photocurrent without deploying an electric voltage. [13] Brown University researchers have demonstrated for the first time a method of substantially changing the spatial coherence of light. [12]
