| 1 | A Heterolayered Fe-based Silicide Superconductor Related Papers Related Patents Related Grants Related Venues Related Experts View Highlight: However, the discovery of new superconductors often occurs by chance from a wide range of materials largely due to the lack of understanding of the true nature of superconductivity. Significantly, the discovery of cuprate and Fe-based superconductors, many of which contain heterolayered building blocks of [CuO 2] 2- and [FeAs] – layers respectively, suggests a rational design approach for unconventional superconductors by combining functional layers with non-magnetic spacer layers, indicating the potential for a systematic approach to discovering new superconductors Here we demonstrate an encouraging example of this strategy with a newly synthesized Fe-based Heterolayered Silicide, Y 4FeSi 8, in single-crystal form. |
