Impact of Disorder on Microscopic Superconducting and Normal‐State Responses in a Kagome Metal

Advanced Functional Materials, EarlyView.
Using depth‐resolved, field‐ and pressure‐dependent μSR$\umu{\rm SR}$ measurements, we show that disorder in Ta‐doped KV3Sb5 drives a crossover from nodal to nodeless superconductivity while strongly modifying the normal‐state magnetic response. Our results reveal that disorder affects superconductivity and magnetism in fundamentally different ways ...

Observation of topological surface states in the high-temperature superconductor MgB2 [PDF]

, 2019
Most topological superconductors known to date suffer from low transition temperatures (Tc) and/or high fragility to disorder and dopant levels, which is hampering the progress in this promising field.
