Atomic-scale control of spin transport in exchange-coupled molecules
A. Fétida, R. Robles, F. Scheurer +4
Spin transport between coupled spins is governed by tunneling and exchange interactions, yet their microscopic relation in real space has remained experimentally elusive. To addres…

Two molecular devices for superconducting spintronics
Cristina Mier, Alex Fétida, Roberto Robles +5
We create two molecular devices with superconducting junctions, using nickelocene molecules, single Fe atoms, and Pb electrodes at low temperature. We find contrasting behavior bas…

Single-spin quantum sensing: A molecule-on-tip approach
A. Fétida, O. Bengone, M. Romeo +4
Quantum sensing is a key component of quantum technology, enabling highly sensitive magnetometry. We combined a nickelocene molecule with scanning tunneling microscopy to perform v…
