      abstract     = {Controlling spin-polarized currents at the nanoscale is of
                      immense importance for high-density magnetic data storage
                      and spin-based logic devices. As electronic devices are
                      miniaturized to the ultimate limit of individual atoms and
                      molecules, electronic transport is strongly influenced by
                      the properties of the individual spin centers and their
                      magnetic interactions. In this work, we demonstrate the
                      precise control and detection of spin-polarized currents
                      through two coupled spin centers at a tunnel junction by
                      controlling their spin–spin interactions. We attach a
                      nickelocene (Nc) molecule to a scanning probe tip and place
                      it over a spin center (either an Fe atom or another Nc
                      molecule) located on a surface. By changing the adsorption
                      orientation of Nc at the tip apex and adjusting the
                      tip–sample distances, we control the wave function overlap
                      between two spin systems, resulting in strong changes in
                      their magnetic exchange coupling, quantum spin states, and
                      spin excitation energies. Coupling the Nc molecule to the
                      surface spin induces exchange-split spin states, enabling
                      the quantitative determination of the spin polarization of
                      tunnel currents. Strongly asymmetric tunneling spectra
                      reveal almost $100\%$ spin-polarized currents through the
                      coupled Nc-Fe spin system. Our findings highlight the
                      potential of these spin systems at the tunnel junction for
                      high-performance spin-based devices engineered at the atomic
                      scale.},
