      abstract     = {We have studied the effect of Cr capping on the magnetic
                      properties of Co nanoparticles (NPs). The NPs have an
                      average diameter of 2.2 nm. The blocking temperature T B
                      of the bare Co particles is 13.2 K. By capping with a thin
                      Cr layer up to a thickness of t Cr  = 0.52 nm, we
                      first observe a decrease of T B up to t Cr  = 0.14 nm,
                      followed by an increase of T B for larger thicknesses
                      0.14 nm ≤ t Cr ≤ 0.52 nm. X-ray magnetic circular
                      dichroism measurements at the resonant Co and Cr L 3 edges
                      confirm a magnetic polarization of Cr which is opposite to
                      the magnetization of Co. The antiparallel alignment of Co
                      and Cr spins at the Co/Cr interface can explain the decrease
                      at low capping layer thickness. However, for larger Cr
                      capping layer thicknesses, the Cr film bridges the Co NPs,
                      mediating interparticle exchange coupling and enhancing
                      dipolar coupling that leads to an increase of the blocking
