A micromagnetic model of metal-evaporated tape

Asymmetry of magneto-optical Kerr effect loops of Co nano-columns grown by oblique incident angle deposition

“…The slanted loops shown in Fig. 3 may be due to the magnetostatic interaction between column structures and indicate that the magnetization rotation is incoherent and a dispersion of the easy axis exists [17,18]. However, the asymmetry of coercivity measured at azimuthal angles that are 1801 apart was not observed for thinner films of $100 nm thick although these films show the similar in-plane anisotropy as the $300 nm films do.…”

Magnetization reversal in an obliquely oriented metal evaporated tape

“…Based on algorithms of increasing sophistication [24] micromagnetic calculations have been used recently to address several issues relative to the ME tapes. These issues range from establishing the variation of magnetization from top to bottom of the magnetic layer [25] or the link between the magnitude of exchange coupling and the degree of co-operative reversal in the columns of crystalline grains [26]. It is our hope that the present experimental information will be used as input on which to base micromagnetic calculations or at least as a litmus test for the calculated results.…”
