“…In the trilayer samples A and B, the contribution of the different mechanisms to the interaction between FeNi layers is dependent on the non‐magnetic‐spacer thickness. These mechanisms include the exchange interaction, the “orange peel” magnetic interaction and the magnetostatic interaction conveyed by “magnetization ripples” 15. The regular magnetic domain patterns observed in multilayered sample C could imply the reduction of the effectiveness of these mechanisms (due to smoother interfaces or an averaging out of the interactions) or the prevalence of other mechanisms as the magnetostatic interaction between layers.…”

Magnetic multilayers consisting of magnetic FeNi and non‐magnetic Ti layers were prepared by rf‐sputtering. Magnetic measurements and magnetic domain structure observations were used for characterization of the samples. The magnetoimpedance performance of FeNi/Ti‐based multilayers is evaluated in terms of the magnitude of the effect and its sensitivity with respect to applied magnetic field. The results show that the trilayer with Ti layer of 6 nm (sample A), deposited to avoid the possibility of appearance of a trascritical state, performs better than the sample with a 10 nm Ti layer (sample B). The best results are obtained with [FeNi/Ti]5/FeNi multilayered structure (sample C) reaching a value of about 60% of variation of the impedance at 180 MHz and a sensitivity of about 22%/Oe at 180 MHz.

“…It is logical to suppose that the domain walls situated in different magnetic layers form magnetic structures with a closed or partially closed magnetic flux. Such a structure formation can be associated with a decrease of the energy density corresponding to the domain wall and as a consequence results in a decrease of the coercivity [3,12].…”

Abstract. The microstructure, anisotropic magnetoresistance, magnetic properties and magnetic domain structure of sputtered FeNi films and [Ti/FeNi] n (n = 2-16) multilayers were comparatively analyzed. It was found that although the grain size increases with an increase of the FeNi thickness both in the case of FeNi films and [Ti/FeNi] n multilayers, it did not exceed 25 nm. The values of anisotropic magnetoresistance for FeNi films and [Ti/FeNi] n multilayers were close to each other showing a weak dependence on the total thickness of the multilayered structure. Coercivity for multilayers was found to be smaller than the coercivity of single layer FeNi films. Despite the absence of a direct exchange interaction between FeNi neighboring layers in the [Ti/FeNi] n structures, their domain structures were found to be quite different from magnetic domains in single layer films due to stray field compensation in the multilayers. Obtained results are useful for the development of sensitive elements for small magnetic field detectors and planar inductors.

“…This layer of the small thickness may have a lack of magnetic anisotropy to prevent magnetization reversal layer permalloy, or even be magnetically disordered. Based on the dependence (L), one can assume that antiferromagnetism in the FeMn layer is present, but weakens in process decrease L. Otherwise, the existence of the paramagnetic layer between the ferromagnetic layers should lead to significantly lower values of H [5].…”

In this work peculiarities of the hysteresis properties formation in permalloy layers included in Fe 20 Ni 80 /FeMn/Fe 20 Ni 80 films were investigated. Temperature dependencies of magnetization reversal parameters were analyzed in the temperature range 5-300 K for samples with various FeMn thickness (2÷4 nm). Conditions of the exchange bias emergence were determined. Magnetic history was shown to have a significant effect on the magnitude and the character of the exchange bias.
