Investigation of Yu-Shiba-Rusinov states of magnetic structures on the surface of β-Bi2Pd superconductor — •Stefano Trivini, Jon Ortuzar, Javier Zaldivar, and Nacho Pascual — CICnanoGUNE, San Sebastiàn, Spain

Magnetic atoms deposited on superconductors induce a pair breaking effect that reflects in intragap states known as Yu-Shiba-Rusinov (YSR) states.[1]

Through their interaction with the substrate, the atoms can be magnetically coupled between each other. This magnetic interaction is reflected in the YSR sub gap structure.[2]

While the effect of magnetic coupling of atoms in extended wires on their Kondo interaction[2] or spin excitation[2] has been previously addressed, the behavior on their YSR is still being investigated.

Here, we do atomic manipulation of magnetic adatoms on β-Bi2Pd by low temperature STM, building atomically perfect magnetic structures. The YSR states can be measured by means of STS with a β-Bi2Pd superconducting tip with 100 ueV energy resolution.
