Researchers have achieved a new record for the highest elemental superconducting transition temperature by reaching 36 K in elemental scandium (Sc) under high pressure. The study provides insights into the relationship between the structure of elemental materials and their superconducting properties, opening up possibilities for discovering high-temperature superconducting materials in simple systems.
Researchers have observed signatures of superconductivity in single crystals of La3Ni2O7 under high pressure, with a maximum transition temperature (Tc) of 80 K. The superconducting phase exhibits an orthorhombic structure and involves the mixing of Ni cations' orbitals with oxygen 2p orbitals. Density functional theory calculations suggest that superconductivity emerges coincidently with the metallization of certain bonding bands. This discovery provides important clues for understanding high-transition-temperature superconductivity in Ruddlesden-Popper double-layered perovskite nickelates and offers a new family of compounds to investigate the mechanism behind high-Tc superconductivity.
Scientists from TU Wien and universities in Japan have used computer simulations to identify palladium as the optimal material for achieving the highest transition temperatures in superconductors. Palladium's weaker electronic interaction compared to nickel and copper places it in the "golden zone" of medium interaction, making it a promising candidate for creating even better superconductors. The research could usher in a new "age of palladates" in superconductivity research and revolutionize the way we generate, transport, and use electricity.
