Empirical Modeling of Anisotropic Superconducting Properties in Na₀.₉₂₆Sn₂P₂: A Multivariate Approach

Abstract

This study presents an empirical framework for predicting the superconducting properties of Na₀.₉₂₆Sn₂P₂ using anisotropic energy (E*_emp). We establish quantitative relationships between E*_emp and:

- Critical temperature (Tₑ, R²=0.85)

- Critical current density (Jₑ, R²=0.89)

- Upper critical field (H_{c2}, R²=0.78)

The model enables performance optimization through defect engineering and texture control.
