It sounds like you’re interested in learning about a “deep feature” of , but I’m not sure exactly which aspect you’d like to explore. Could you let me know a bit more about what you have in mind?
The specific‑heat jump at T_c is ΔC/γT_c ≈ 2.1, significantly exceeding the BCS weak‑coupling value of 1.43, suggesting strong‑coupling superconductivity. Low‑temperature C_p(T) fits to C = γT + βT³ give and β = 0.72 mJ mol⁻¹ K⁻⁴ (Debye temperature Θ_D ≈ 265 K).
Plate‑like crystals up to 4 mm × 4 mm × 0.2 mm were harvested and stored under inert atmosphere.
