“…Another possible application concerns ferromagnetic thin films of Mn 5 Ge 3 that were recently synthesized [19,20]. Our model unifies previous results for materials with strong anisotropy (Q > 1) [2,3,4] and those with medium anisotropy ( 1 2 Q < 1) [11], containing them as special cases. The explicit treatment of the domain wall is an important improvement with respect to the Kittel model since it allows the determination of the in-plane remanent magnetization, which is important for the analysis of experimental data.…”

“…The Kittel model is limited to systems with small quality ratios. However, in many strongly anisotropic materials Q is large and no critical thickness is observed [4,18,23]. [6,7], it separates the homogeneous state without domains from the weak stripe phase.…”

“…The ratio 2K/(µ 0 M 2 0 ) (in SI units) is also known as the quality factor Q and the magnetization direction remains perpendicular to the surface for all values of film thickness for Q > 1. Numerous theoretical and experimental works have been devoted to such materials with strong perpendicular magnetic anisotropy [2,3,4]. It has been shown that in such materials the domain width has a minimum as a function of film thickness, increasing towards smaller or larger thicknesses.…”

“…We adopt a sinewave magnetization profile in the wall and we take into account the magnetostatic interaction between the top and bottom surfaces of the film. Our model applies to hexagonal Co, for which a critical thickness between 25 nm [15,16] and 40 nm [17] has been reported, as well as to materials with high magneto-crystalline anisotropy, such as FePd(001) or garnet films [4,17,18]. Another possible application concerns ferromagnetic thin films of Mn 5 Ge 3 that were recently synthesized [19,20].…”

Abstract.For uniaxial easy axis films, properties of magnetic domains are usually described within the Kittel model, which assumes that domain walls are much thinner than the domains. In this work we present a simple model that includes a proper description of the magnetostatic energy of domains and domain walls and also takes into account the interaction between both surfaces of the film. Our model describes the behavior of domain and wall widths as a function of film thickness, and is especially well suited for the strong stripe phase. We prove the existence of a critical value of magneto-crystalline anisotropy above which stripe domains exist for any film thickness and justify our model by comparison with exact results. The model is in good agreement with experimental data for hcp cobalt.

“…However, there has been little work on ͓Co/ Pt͔ n multilayers with an intermediate n, although several papers reported other materials with PMA and intermediate thickness. [11][12][13] In this work, we have studied in detail the magnetization reversal behavior of ͓Co͑4 Å͒ /Pt͑10 Å͔͒ 4 multilayers with an intermediate n = 4, and revealed very unusual reversal behavior. The reversal has been studied macroscopically by vibrating-sample magnetometry ͑VSM͒, and microscopically by both magneto-optical Kerr effect ͑MOKE͒ microscopy 9,14,15 and magnetic force microscopy ͑MFM͒ imaging.…”

Unusual magnetization reversal in [Co∕Pt]4 multilayers with perpendicular anisotropy

Unusual magnetization reversal of ͓Co͑4 Å͒ /Pt͑10 Å͔͒ 4 multilayers with perpendicular magnetic anisotropy has been revealed macroscopically by magnetometry measurements and microscopically by magneto-optical Kerr effect microscopy and magnetic force microscopy ͑MFM͒ imaging. During the first-order reversal process, the magnetization first decreases, then reaches a plateau, and finally rises back to saturation, corresponding to expanding bubble domains, stationary domains, and fading contrast but unchanged boundary domains, respectively. MFM imaging reveals the existence of many submicron-scaled unreversed channels within the boundary of the "bubble" domains. The magnetization reversal behavior can be accounted for by the evolution of the unusual domain structures in different field regimes.

Single‐crystalline antiferromagnetic artificially layered [Ni/Mn] films of different thicknesses, covered by ferromagnetic Co layers, are deposited on . Their structural and magnetic properties are characterized by low‐energy electron diffraction (LEED) and magneto‐optical Kerr effect, respectively, and compared with disordered alloy films with the same Ni/Mn ratio and the same film thickness. LEED intensity‐versus‐energy curves show that the perpendicular interatomic lattice distance is decreased in the artificially layered [Ni/Mn] samples in comparison to the disordered alloy films. At the same time, the artificially layered [Ni/Mn] films exhibit higher coercivity and exchange bias of the adjacent Co layer compared to those of . This is discussed as a consequence of the different interatomic lattice distance, presumably caused by an ordered buckling in the artificially layered [Ni/Mn] samples, leading to a stronger interlayer exchange coupling.
