“…There has been recently renewed interest in the magnetic properties of nanocomposite materials that consist of very fine magnetic particles embedded in a metallic or dielectric nonmagnetic host [1][2][3][4][5][6][7] and in nanocomposite materials that consist of multilayers with very thin magnetic layers [8,9] which exhibit certain superparamagnetic (SPM) properties, too. If the dimension of a magnetic particle is reduced drastically, to a few nanometers, the domains in the particle merge into a single one, creating what is known as a single-domain particle and the total magnetic moment is the sum of all moments of the atomic particle.…”

A system of nano sized modomain ferromagnetic particle arranged in two-dimensional lattice is theoretically investigated. The basic aim of the investigation is to find the ground state of these types of models where the interaction is long-ranged and anisotropic. The numerical calculations show that for some lattices there is a number of degenerated states near the zero temperature. The ground state of these systems is basically of a complicated antiferromagnetic type.

Abstract-The strip-line frequency-domain technique for permeability measurement is compared to the field domain technique. The combined setup for microwave measurement of thin film permeability with both techniques is proposed. The field-domain technique is less affected by inhomogeneity of measurement strip cell and has significantly higher signal-to-noise ratio, but the obtained parameters are affected by film thickness and may differ from that of the frequency-domain technique. Analysis of the field-domain data obtained at a set of frequencies makes it possible to determine the saturation magnetisation, the anisotropy field and the damping factor without the knowledge of the amount of substance under study. In case of a simple permeability spectrum the data on metal thickness make it possible to estimate the effective skin-depth as well. The technique is tested by simulation and is applied to determine permeability of Fe-based films vacuum-sputtered on glassceramic and polymer substrates.

“…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.…”

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

To improve the high-frequency properties of Fe-based thin films, doped and pure Fe thin films were obliquely deposited on Si (100) substrate by RF-magnetron sputtering. Vibrating sample magnetometer (VSM) measurements show obvious in-plane uniaxial magnetic anisotropy in both doped and pure Fe thin films, and enhancement effects of doping on Soft magnetic properties were also observed. Microwave permeability measurements indicate that the resonance frequency and permeability of pure Fe films are much larger than those of doped Fe thin films. Damping factors of Fe thin films deposited at different oblique angles were further investigated.
