TL;DR

This paper computationally explores multi-element materials with Z=7.33, derived from combinatorial synthesis of systems with Z=4.67, 10, and 12.67, proposing they could exhibit high-temperature superconductivity above 39K.

Contribution

It introduces a novel computational approach to identify multi-element Z=7.33 materials that meet the MgB2 superconductivity model, expanding beyond binary and ternary systems.

Findings

Identified over 300 potential Z=7.33 superconducting materials.

Proposed these materials could have Tcs higher than 39K.

Demonstrated the feasibility of combinatorial synthesis for high-Tc superconductor discovery.

Abstract

The search for MgB2-like superconductivity has before now been limited to binary and ternary systems. However systems with more-than-three-elements that meet the MgB2 model have yet to be investigated either computationally or experimentally. Here we show that through computational synthesis of two binary or ternary materials from the Z=4.67, 10 and 12.67 families, we can get Z=7.33 systems with more-than-three elements. We have identified over 300 of such possibilities for further studies. We propose that the resultant combinatorial synthesis of such Z=7.33 systems with more-than-three-elements and that meet the MgB2 model will be superconducting with Tcs higher than 39K.
