“…More generally, the hysteresis loops are unchanged whatever the orientation of the applied in-plane magnetic field. It is typical of thin films with perpendicular anisotropy exhibiting a weak stripe domain structure [9,10]. The coercive field is 40.2 Oe and the saturation field is 400 Oe in this film.…”

“…A considerable number of theoretical and experimental works [9][10][11][12] have been devoted to the transition as a function of the relevant magnetic parameters of the material (anisotropy constant), the thickness of the magnetic layer. But these reports almost focus on nanocrystalline films, such as rare earth doped 3d transition metal films.…”

“…The film exhibits in-plane anisotropy due to dominant shape anisotropy. It is noted that the in-plane hysteresis loop of the film has noticeable characteristics of the so-called as transcritical hysteresis loops, which is an indication of the appearance of perpendicular anisotropy exhibiting a weak stripe domain structure [2][3][4][5][8][9][10]. Furthermore, from the area between the two normalized magnetization curves, we obtained the effective anisotropy field: H eff k = 2(K u − 2πM 2 s )/M s = −5000Oe, in which, 4πM s = 11, 923 Gs.…”

“…In the earlier studies, the stripe domain magnetic structure has been obtained in Ce 9 Fe 91 [2] and Fe 0.73 (Sm 2 O 3 ) 0.27 films [3] when the film thickness is higher than a critical thickness (t c ). L Sun reports that with the addition of Gd and Tb, the easy axis of the perpendicular uniaxial anisotropy evolves from film plane to film normal [1].…”

CeO 2 ) 14 Fe 86 films were fabricated by a radio frequency magnetron sputtering method at different substrate temperature. The results reveal that the films deposited at substrate temperature lower than 773 K exhibit a strong perpendicular anisotropy, and the correlated dynamic permeability spectrum measured over the frequency range of 0.5-7 GHz shows a high resonance frequency. The study on the relation R ∼ T shows that the resistivity of the thin film has a minimum near room temperature and tends to saturation as the temperature approaches zero, exhibiting a behavior reminiscent of Kondo scattering. However, as the substrate temperature increases to 973 K, the films possess an in-plane anisotropy and lower H c . The resistivity exhibits a transition from metal to insulator characterized by a maximum of resistivity at 220 K.

“…The large permeability (µ) and high resonance frequencies (fr) of these films have been attributed mainly to their large uniaxial magnetic anisotropy field (Hk) and saturation magnetization (Bs) 1)-3) . However, there have been few reports 4), 5) without any uniaxial magnetic anisotropy.…”

Effect of Perpendicular Magnetic Anisotropy on the High Frequency Soft Magnetic Properties of Co-Al-N Films

2012

The high frequency soft magnetic properties (µ-f properties) of magnetically isotropic Co-Al-N films have been investigated. The Co-Al-N films with a Co content of around 80 at.% were prepared by the rf-sputtering method to change the distance between target and substrate (dT-S). The magnetization curves reveal that the films have a perpendicular magnetic anisotropy and are magnetically isotropic in the film plane. The saturation magnetic field (Hs) can be changed from 120 to 640 Oe as dT-S increases from 40 to 80 mm. The films show a stripe domain with a domain width of 400-500 nm, which decreases as increasing the perpendicular magnetic anisotropy increases. The films exhibit excellent µ-f properties, and their permeability keeps constant up to a few GHz and shows a clear peak at resonance frequency (fr), which shifts from 0.75 to 2.4 GHz correspond to the magnitude of their Hs.
