Nanoscale Superconducting States in the Fe-Based Filamentary Superconductor of Pr-Doped CaFe₂As₂

The low-temperature scanning tunneling microscope and spectroscopy (STM/STS) are used to visualize superconducting states in the cleaved single crystal of 9% praseodymium-doped CaFe₂As₂ (Pr-Ca122) with <i>T_c</i> ≈ 30 K. The spectroscopy shows strong spatial variation...
