“…Considering that the domain wall exits in the film and the out-of-plane stray field cannot be detected through MFM, we can conclude that all of the magnetic moments lie in the film plane, and the domain wall is Néel wall. Note that, the Co 81 Ir 19 layer thickness is 50 nm which is higher than that of the reported Fe-and Co-based soft magnetic films 18 19 20 21 22 .…”

“…The domain wall assumes the form of Néel wall (the magnetic moments strictly lie in the film plane in the domain wall district) when the film is thin and it will become Bloch wall (an out-of-plane stray field exists in the domain wall district) when the film thickness exceeds a critical value. In conventional Fe- and Co-based soft magnetic films, this critical value is approximately 20–40 nm 18 19 20 21 22 . If the magnetocrystalline anisotropy energy is introduced to the soft magnetic film, the domain wall energy of Bloch wall expressed in eq.…”

This study investigated the magnetic domain walls in a single-layer soft magnetic film with strong magnetocrystalline anisotropy energy. The soft magnetic film is composed of a highly c-axis-oriented hcp-Co81Ir19 alloy with strong negative magnetocrystalline anisotropy. The domain structure of the soft Co81Ir19 films with thickness ranging from 50–230 nm in a demagnetization state was observed through magnetic force microscopy and Lorentz transmission electron microscopy. Results reveal that the critical transition thickness at which the domain wall changes from Néel type to Bloch type is about 138 nm, which is much larger than the critical value of traditional Fe- and Co-based soft magnetic films with negligible magnetocrystalline anisotropy. Theoretical calculation was also performed and the calculated result agrees well with experimental data.

“…As an example, Fig. 3 shows the dependencies l 0 (x/ x 0 ) and l 00 (x/x 0 ) for several points within the limits of the periods k. This dependencies were calculated for reasonable values of the parameters: H k = 20 Oe, H dc = 0, b 0 = 2.0°, 4pM = 1.7 · 10 4 Cc, a = 0.01, which are typical for ultra-soft magnetic thin films [6,7]. For comparison with experimental data on the frequency dependence of the magnetic permeability, Eqs.…”

“…The local oscillation of the magnetization is observed as a ripple structure in a defocused film image in the Lorentz Transmission Electron Microscopy (LTEM) in the Fresnel mode [4,5]. We have shown that the amplitude of the oscillations can be obtained from an analysis of the LTEM ripples [6]. Our approach is based on the Landau-Lifshitz equation where the effective field includes the internal stray field estimated from the LTEM observations.…”

Results on the investigation of the magnetic properties and microstructure of the as-deposited and annealed at T = 200-700 o C Fe-Zr-N films are presented. The Fe-Zr-N films with the 0.7-µm thickness were deposited by RF sputtering onto glass square substrates. Structural properties of the films were studied by means of the X-ray diffraction technique. The bulk magnetic characteristics of the films have been measured by a vibrating sample magnetometer (VSM). The study of the near-surface magnetic properties of the Fe-Zr-N samples was carried out employing magneto-optical micromagnetometer with a surface sensitivity of about 20 nm of the thickness depth. The strong annealing effect on the values of the coercivity H C and the saturation field H S of the films was revealed. The values of H C and H S of the films, annealed at T = 450 and 500 o C, were found to be minimal. The temperature dependences of H C and H S were explained by microstructure changes of the studied films after their post-deposition heat treatment.
