Study identifies mechanism holding electron pairs together in unconventional superconductors

With the spin fluctuations in the centre, the theoretical description becomes most meaningful. Credit: Vienna University of Technology Depending on the perspective one chooses, a theoretical calculation can describe observed physics more or less accurately. Back in 2015, Alessandro Toschi from the Institute of Solid State Physics at TU Wien and his team, within an … Read more

Study finds nickelate superconductors are intrinsically magnetic

A muon, center, spins like a top within the atomic lattice of a thin film of superconducting nickelate. These elementary particles can sense the magnetic field created by the spins of electrons up to a billionth of a meter away. By embedding muons in four nickelate compounds at the Paul Scherrer Institute in Switzerland, researchers … Read more

New leap in understanding nickel oxide superconductors

An illustration shows a type of quantum matter called charge density waves, or CDWs, superimposed on the atomic structure of a nickel oxide superconductor. (Bottom) The nickel oxide material, with nickel atoms in orange and oxygen atoms in red. (Top left) CDWs appear as a pattern of electron ripples, with a higher density of electrons … Read more
