(a) The magnetic susceptibilities of all crystals under zero-field cooling (ZFC) and field cooling (FC, H along the c-axis) show that sharp diamagnetic transitions occur at around 40 K for all samples. (b) Temperature dependence of in-plane resistivity for all crystals. The inset is the zoom-in view around the superconducting transition temperature.
