      abstract     = {Magnetic high-entropy alloys (HEAs) are a new category of
                      high-performance magnetic materials, with multicomponent
                      concentrated compositions and complex multi-phase
                      structures. Although there have been numerous reports of
                      their interesting magnetic properties, there is very limited
                      understanding about the interplay between their hierarchical
                      multi-phase structures and the resulting magnetic behavior.
                      We reveal for the first time the influence of a
                      hierarchically decomposed B2 + A2 structure in an
                      AlCo0.5Cr0.5FeNi HEA on the formation of magnetic vortex
                      states within individual A2 (disordered BCC) precipitates,
                      which are distributed in an ordered B2 matrix that is weakly
                      ferromagnetic. Non-magnetic or weakly ferromagnetic B2
                      precipitates in large magnetic domains of the A2 phase, and
                      strongly magnetic Fe-Co-rich interphase A2 regions, are also
                      observed. These results provide important insight into the
                      origin of coercivity in this HEA, which can be attributed to
                      a complex magnetization process that includes the successive
                      reversal of magnetic vortices.},
