Revealing the energy and spatial characteristics of impurity-induced states in superconductors is essential for understanding their mechanism fabricating a new quantum state by manipulating impurities. Here, using high-resolution scanning tunneling microscopy spectroscopy, we investigate distribution magnetic field response impurity $({\text{Li}}_{1\ensuremath{-}x}{\text{Fe}}_{x})\text{OHFeSe}$. We detect two pairs strong in-gap on ``dumbbell-shaped'' defects. They display damped...
The interface between magnetic material and superconductors has long been predicted to host unconventional superconductivity, such as spin-triplet pairing topological nontrivial state, particularly when spin-orbital coupling (SOC) is incorporated. To identify these states, fabricating homogenous heterostructures that contain various properties are preferred but often challenging. Here, we synthesized a trilayer-type van der Waals heterostructure of MnTe/Bi 2 Te 3 /Fe(Te, Se), which combined...

Vortex pinning is a crucial factor that determines the critical current of practical superconductors and enables their diverse applications. However, underlying mechanism vortex has long been elusive, lacking clear microscopic explanation. Here, using high-resolution scanning tunneling microscopy, we studied single induced by point defect in layered FeSe-based superconductors. We found defect-vortex interaction drives low-energy bound states away from <a:math...
