“…A lot of work in material science has been done over many years to examine how magnetic parameters are influenced by the composition and micro structure of thin films [1][2][3][4][5][6][7][8][9] .Models of disordered ferromagnets were studied analytically by Ignatchenko and co-workers in the late 1970s and early 1980s (see 10 and references therein) as well as by Kronmüller and coworkers 12 . They derived "laws of approach of the magnetization to saturation".…”

I present a study of the influence of disorder in thin magnetic films on the switching behavior of small magnetic cells of well defined shape and size. The disorder considered arises from randomly oriented crystalline grains of different shape, size, and crystalline orientation which gives rise to locally fluctuating intrinsic anisotropy directions and strengths. The study comprises a theoretical investigation of a disordered Stoner Wohlfarth model, as well as micromagnetic simulations. I show that the fluctuations in the total anisotropy and therefore in the switching fields are controlled by a single dimensionless parameter. The theoretical findings are well confirmed by micromagnetic simulations of many different samples.PACS numbers: 85.75.B, 85.70.K, 75.75
