      abstract     = {Antiferromagnetic (AFM) skyrmions have emerged as a highly
                      promising avenue in the realm of spintronics, particularly
                      for the development of advanced racetrack memory devices. A
                      distinguishing feature of AFM skyrmions is the cancellation
                      of their net topological charge, leading to an anticipated
                      absence of the skyrmion Hall effect (SkHE). Here, we unveil
                      that the latter is finite under the influence of
                      spin-transfer torque, depending on the direction of the
                      injected current impinging on intrinsic AFM skyrmions
                      emerging in Cr/Pd/Fe trilayer on Ir(111) surface. Hinging on
                      first principles combined with atomistic spin dynamics
                      simulations, we identify the origin of the SkHE, which is
                      due to the ellipticity of the skyrmions, and we uncover that
                      FM skyrmions in the underlying Fe layer act as effective
                      traps for AFM skyrmions, confining them and affecting their
                      velocity. These findings hold significant promise for
                      spintronic applications, the design of multi-purpose
                      skyrmion tracks while advancing our understanding of
                      AFM–FM skyrmion interactions and hybrid soliton dynamics
                      in heterostructures.},
