Analysis reveals strong correlation of magnetic anisotropy and binding energy with negative thermal expansion in superconductors.
We present a systematic analysis combining computed interatomic potential energy curves and magnetic anisotropy (E*) with experimental negative thermal expansion (NTE) in CoZr₂ and FeZr₂. Our results show strong correlation: FeZr₂ exhibits deeper binding energy wells, stronger magnetic anisotropy, and more pronounced NTE. These insights pave the way for designing superconductors with tailored thermal-mechanical properties
