The antagonistic nature of magnetism and superconductivity gives rise to
exotic phenomena, such as quantum levitation or unconventional pairing. At the
scale of single magnetic adatoms, they combine to form spin-polarized Shiba
states. In this work, we show how these states can be tuned and what kind of
information can be extracted from their excitation spectra. Furthermore, from
the analysis of the Shiba wavefunction, we characterize inter-band scattering
events in β-Bi2Pd, a superconductor with multiple bands crossing the Fermi
level, and identify the presence of spin-polarized bands in the
superconducting condensate.
