      abstract     = {Spin-bearing molecules can be stabilized on surfaces and in
                      junctions with desirable properties, such as a net spin that
                      can be adjusted by external stimuli. Using scanning probes,
                      initial and final spin states can be deduced from
                      topographic or spectroscopic data, but how the system
                      transitions between these states is largely unknown. We
                      address this question by manipulating the total spin of
                      magnetic cobalt hydride complexes on a corrugated boron
                      nitride surface with a hydrogen-functionalized scanning
                      probe tip by simultaneously tracking force and conductance.
                      When the additional hydrogen ligand is brought close to the
                      cobalt monohydride, switching between a correlated S = 1/2
                      Kondo state, where host electrons screen the magnetic
                      moment, and an S = 1 state with magnetocrystalline
                      anisotropy is observed. We show that the total spin changes
                      when the system is transferred onto a new potential energy
                      surface that is defined by the position of the hydrogen in
                      the junction. These results show how and why chemically
                      functionalized tips are an effective tool to manipulate
                      adatoms and molecules and a promising new method to
                      selectively tune spin systems.},
