Description:
Author(s): Bosen Wang, Xuan Luo, Kento Ishigaki, Kazuyuki Matsubayashi, Jinguang Cheng, Yuping Sun, and Yoshiya Uwatoko We report two distinct superconducting states with different crystal structures and a crossover from a type-II to a type-I superconductor (SC) in ( Ba , Sr ) B i 3 . The superconducting parameters are revealed to classify two SCs: BaB i 3 is in the weak-coupling limit on the basis of Δ C / γ n T c ∼ 0.67 and 2 Δ / k B T c ∼ ... [Phys. Rev.
