Soft magnetic materials -- Random magnetic anisotropy model -- Exchange interaction
Аннотация: Coercivity of nanocrystalline magnetic alloys depends on the grain size D according to a power law Hc ∝ Dn with n from 2 to 6. The law Hc ∝ D6 is derived based on the random magnetic anisotropy model and is clearly manifested in experimental studies of some Finemet type alloys. In this letter using computer modeling it is demonstrated that a power-law behavior with the exponent n less than 6 can be due to a grain-size distribution. An increase of grain size variance results in a decrease of the exponent from 6 to the value of about 3.

Chemical deposition -- Coercive force -- Isotropic and anisotropic films -- Trilayer films
Аннотация: Coercivity of amorphous Co-P single-layer and trilayer films fabricated by chemical deposition has been investigated. It has been established that the thickness dependences of the coercivity for isotropic and anisotropic films are different. Data on the coercivity variation with a nonmagnetic spacer thickness and a number of magnetic layers in the trilayer films are reported. The results obtained are analyzed with regard to the features of the induced anisotropy in amorphous ferromagnetic films and the magnetic coupling between magnetic layers in sandwich structures.© (2014) Trans Tech Publications, Switzerland.

multilayer magnetic films -- interlayer interaction -- dipole coupling field -- coercivity
Аннотация: The results of experimental and theoretical studies of the coercivity and the dipole coupling field of the hysteresis loop on the thickness of the nonmagnetic interlayer in magnetic films, which are obtained via chemical deposition, are presented. Using model calculations based on the Landau–Ginzburg equations, the exchange interactions between magnetic layers with the participation of atoms from the nonmagnetic interlayer are studied. The resulting expression for the dipole coupling field describes well the exponential changes in the dipole coupling field as a function of the interlayer thickness in structures with both soft magnetic layers and layers with significantly different values of the coercivity.

sandwich structure -- exchange bias -- coercivity -- magnetization reversal
Аннотация: Exchange bias and coercivity of the hysteresis loop of a low-coercive layer in magnetic three-layered structure prepared by chemical deposition are studied. It is established that the coercive force in the films obtained nonmonotonically changed with the low-coercive layer thickness. The specificity of magnetization reversal of exchange-biased layers is analyzed.

Composition modulated materials -- Multilayer films -- Composite powders -- Anisotropy field -- Coercivity -- Electroless deposition
Аннотация: The comparison between the magnetic properties of materials with different curvature and spatial distribution of nanograins, such as particles (3D spatial distribution) and multilayer films (2D) was carried out. Functionally graded Co(P)/Ni(P) and Co(P)/CoNi(P) specimens have been fabricated by electroless deposition. The magnetic and structural properties are characterized by electron microscopy, X-ray diffraction, ferromagnetic resonance spectroscopy, and vibrating sample magnetometer. It was demonstrated that the interaction between the Ni(P) core and Co(P) shell of particles could form the functionally graded materials with tailored structure and coercive force. Furthermore, it was found that the magnetic parameters (the local anisotropy field, ferromagnetic resonance linewidth, and coercivity) are mainly determined by the artificially created interface boundaries for all grains’ spatial distribution. The magnetic anisotropy field and coercivity of Co(P)/Ni(P) flat films were characterized by lower values than those for spherical shell of particles with the same composition, produced by the same method.

NiO nanoparticles -- Pulsed field magnetization -- Coercivity
Аннотация: The dynamic magnetization switching of antiferromagnetic nickel oxide nanoparticles with a characteristic size of 8 nm has been experimentally investigated by pulsed field magnetometry. It is shown that, due to the presence of defects in NiO nanoparticles, as in other antiferromagnetic particles, the uncompensated magnetic moment is induced by the incomplete compensation of spins at the antiferromagnetic ordering. The dynamic magnetic hysteresis loops have been studied in pulsed fields with the maximum field (Hmax) of up to 130 kOe and pulse lengths (τP) of 4, 8, and 16 ms. According to the results obtained, the coercivity (HC) depends on both the τP and Hmax values. The observed increase in the HC value with decreasing pulse length (i.e., with increasing switching field frequency) is unambiguously related with the relaxation processes typical of single-domain ferromagnetic nanoparticles. However, the observed effect of the maximum applied field (Hmax) on the HC value is assumed to be a feature of antiferromagnetic nanoparticles.

Кл.слова (ненормированные):
nanoparticles -- cobalt ferrite -- magnetodynamics -- superparamagnetism -- effective anisotropy
Аннотация: We report a study of the magnetodynamics of cobalt ferrite (CoFe2O4) nanoparticles with an average diameter of ~6 nm. Hysteresis loops were measured under quasi-static conditions and in pulse fields with amplitudes H0 of up to 130 kOe and for durations τP of 8 and 16 ms. The growth of coercivity Hc observed with an increase in the magnetic field variation rate dH/dt (determined by the values of H0 and τP) and the reduction of Hc with temperature is ascribed to the superparamagnetic effect. The proposed theoretical model explains the observed dependences fairly well. Notably, the effective magnetic anisotropy constant obtained exceeds the value for bulk crystals and might be indicative of the contribution of surface magnetic anisotropy.
