      abstract     = {The role of the crystal lattice, temperature and magnetic
                      field for the spin structure formation in the 2D van der
                      Waals magnet Fe5GeTe2 with magnetic ordering up to room
                      temperature is a key open question. Using Lorentz
                      transmission electron microscopy, we experimentally observe
                      topological spin structures up to room temperature in the
                      metastable pre-cooling and stable post-cooling phase of
                      Fe5GeTe2. Over wide temperature and field ranges, skyrmionic
                      magnetic bubbles form without preferred chirality, which is
                      indicative of centrosymmetry. These skyrmions can be
                      observed even in the absence of external fields. To
                      understand the complex magnetic order in Fe5GeTe2, we
                      compare macroscopic magnetometry characterization results
                      with microscopic density functional theory and spin-model
                      calculations. Our results show that even up to room
                      temperature, topological spin structures can be stabilized
                      in centrosymmetric van der Waals magnets.},
