Probing magnetic interactions between Cr adatoms on the $\beta$-Bi${}_2$Pd superconductor

Deung-Jang Choi, Carlos García Fernández, Edwin Herrera +6

We show that the magnetic ordering of coupled atomic dimers on a superconductor is revealed by their intra-gap spectral features. Chromium atoms on the superconductor $\beta$-Bi${}_2$Pd…
