      abstract     = {Magnetic thin films and multilayers offer many novel
                      physical phenomena with tremendous potential for
                      applications. Various growth processes and methods are in
                      place to make homogeneous films. However, dispersion in
                      local easy axes is an inherent issue which may give rise to
                      an effective random anisotropy in thin film. It is important
                      to investigate the effect of random anisotropy on the
                      magnetic properties of the thin films. In this report we
                      address the aspect of local dispersion induced random
                      anisotropy on magnetization reversal in ferromagnetic
                      (FM)/non-magnetic(NM)/ferromagnetic(FM) stacks. We show that
                      the magnetization reversal is not only governed by the
                      inter-layer interaction but the intrinsic anisotropies also
                      play a crucial role. In this context we have studied the
                      magnetization reversal of Co//Co trilayers with various
                      thicknesses of which acts as a spacer between the two Co
                      layers. Presence of random anisotropy in addition to growth
                      induced uniaxial anisotropy was observed in all the samples.
                      Magneto-optic Kerr effect (MOKE) based microscopy revealed
                      dipolar-coupled layer-by-layer magnetization reversal of the
                      Co layers which was corroborated by polarized neutron
                      reflectometry (PNR) experiments. Micromagnetic simulations
                      confirmed that the presence of random anisotropy in addition
                      to uniaxial anisotropy leads to layer-by-layer magnetization
                      reversal.},
