“…Every measurement was preceded by a sample saturation along the chosen field direction, followed by field reduction down to the desired value, without crossing the zero, in order to ensure that a single domain state (uniform over the sample surface) is created. This is confirmed by independent Kerr effect imaging [18]. It was also checked that, on homogeneous samples, no depolarization occurs.…”

“…On the other hand, a more complex structure inside the large magnetic domains is visible, in contrast, for example, to the FeNi (40 nm) × 4 multilayered sample (Figure 5). Most likely, this is a consequence of the complex magnetic structure through the thickness of the whole sample [37]. Additional confirmation of this assumption is provided by Kerr images obtained by reversing the magnetization of the sample along the hard magnetization axis (Figure 7b,d).…”

“…This situation is apparently possible if the magnetic structure of the sample is similar to the Bloch-type magnetic wall magnetic structure. A magnetization helix magnetic structure across the sample thickness was previously observed in bilayer films having orthogonal, in-plane easy magnetization axes [37]. (6) (7) (8) (9) (10) 200 μm Some confirmation of the helix-like magnetic structure through the thickness of the whole sample comes from the magnetic hysteresis loop measured from the side of the glass substrate at an angle of 45 • with respect to the expected easy magnetization axis of the first magnetic layer (Figure 8a).…”

FeNi films were prepared using the DC magnetron sputtering technique with an oblique deposition arrangement. Multilayers with different orientations of the magnetic anisotropy axes were obtained thanks to a rotary sample holder inside the vacuum chamber. Magnetic properties were studied using magneto–optical Kerr microscopy and a vibrating sample magnetometer. Single-layered FeNi films having thicknesses as high as 10 nm and 40 nm show in-plane uniaxial easy magnetization axes produced by the oblique incidence of incoming components of the beams. Magnetic anisotropy field for four-layered samples with orthogonal uniaxial magnetic anisotropy axes in the adjacent layers and the thickness of individual layers of 10 nm and 40 nm turned out to be less than in single-layered films. The magnetic properties peculiarities of the eight-layered sample FeNi (10 nm) × 8 obtained by rotation of the sample holder by 45° before deposition of each subsequent layer suggest the formation of a helix-like magnetic structure through the thickness of the multilayered sample similar to the magnetization arrangement in the Bloch-type magnetic domain wall.
