      abstract     = {We demonstrate that magnetic skyrmions with a mean diameter
                      around 60 nm can be stabilized at room temperature and zero
                      external magnetic field in an exchange-biased
                      Pt/Co/Ni80Fe20/Ir20Mn80 multilayer stack. This is achieved
                      through an advanced optimization of the multilayer-stack
                      composition in order to balance the different magnetic
                      energies controlling the skyrmion size and stability.
                      Magnetic imaging is performed both with magnetic force
                      microscopy and scanning nitrogen-vacancy magnetometry, the
                      latter providing unambiguous measurements at zero external
                      magnetic field. In such samples, we show that exchange bias
                      provides an immunity of the skyrmion spin texture to
                      moderate external-magnetic-field perturbations, in the
                      tens-of-millitesla range, which is an important feature for
                      applications such as memory devices. These results establish
                      exchange-biased multilayer stacks as a promising platform
                      toward the effective realization of memory and logic devices
                      based on magnetic skyrmions.},
