Uniaxial anisotropy and high-frequency permeability of novel soft magnetic FeCoTaN and FeCoAlN films field-annealed at CMOS temperatures

Hyperfine interaction studies and magnetic properties of FeCoAlN nanocomposite films

“…Magnetization reversal occurs mainly by coherent rotation of a single domain except of domain formation near the jumps observed on the transversal hysteresis loop. These magnetic properties are comparable with those obtained on field-annealed samples by Seemann et al [7]. Direction of the uniaxial anisotropy is given by the direction of the residual magnetic field from permanent magnets during film deposition.…”

High‐frequency ferromagnetic properties of FeCoZr nanocrystalline films

“…Yu et al presented the magnetic properties of Fe-Zr amorphous alloy and showed that the spin glass state was caused by the nonlinear magnetic couplings between Fe local moments due to the structure disorder [5]. It was also reported that FeCo base alloy revealed high saturation magnetization up to 2.4 T [6][7][8][9]. In this study, Zr was chosen as a dopping element into FeCo high saturation magnetization material to achieve uniaxial anisotropy.…”

Soft magnetic properties and high frequency characteristics of FeM (M = B, Hf, Zr) and pure Fe films fabricated by oblique deposition

“…During the last decade, much research has been carried out to develop magnetic thin film with excellent high frequency characteristics for application to high-frequency devices such as perpendicular media, magnetic recording write heads and thin-film wireless inductor cores [1][2][3][4][5][6][7]. The highfrequency applications of magnetic thin films require the thin films to possess a high saturation magnetization and an appropriately large in-plane uniaxial anisotropy (IPUMA) [8][9][10][11] field to achieve a high cutoff frequency, which is the highest theoretically possible frequency of soft materials.…”
