Ideal gas law-like behavior in chemically-induced superconductors*

Fruitful attempts at understanding superconductors has led to the discovery of numerous empirical relationships concerning their physical properties. This includes, for example, the BNC empirical scaling rule [1], ΔC ~ T_c³, for some iron pnictide superconductors. Where ΔC represents the jump in heat capacity at critical temperature T_c³ . Similar scaling behaviors exist for superconductors in general as well. To date, however, the link between superconductivity and the chemical/structural properties of materials remains poorly understood. Here we report empirical ideal gas law-like relationships between the chemical unit and physical structure of chemically induced superconductors near the onset of superconductivity. [2]
