demagnetizing field -- ferromagnetic resonance -- electroless powders
Аннотация: The two ways of reducing the dispersion of the demagnetizing fields in magnetic powders of cobalt alloys have been tested: the isolation of magnetic particles in nonmagnetic matrix and compaction of the powders. The ferromagnetic resonance (FMR) and the hysteresis loops of the pretreated magnetic powders were investigated. The FMR linewidth is significantly narrowed both with increasing of the nonmagnetic fraction in the samples prepared by the first way and with increasing of relative density of the compacts. The limit case of FMR linewidth in continuous magnetic film there is no dispersion of the demagnetizing fields is in good agreement with discussed data. The hysteresis loops of powder with the particles coated by the non-magnetic phase became narrow and easy saturated with increasing of nonmagnetic phase fraction.

FeCo–C alloy -- electroless deposition -- magnetic properties
Аннотация: The structural and magnetic properties of FeCo–C films produced by electroless plating with differentcarbohydrates as reducing agents have been investigated. The surface morphology and coercivities of FeCo–C films are dependent on the iron content and type of reducing agent. The local magnetic anisotropy field value increases with a decrease in Fe content. For all systems, deposits with good soft magnetic properties were obtained, with coercivities less than 12 Oe and saturation magnetizations close to 240 emu/g for FeCo–C film with 30% cobalt. The best soft magnetic properties corresponded to the deposits with bcc structure and grain sizes less than 20 nm.

    Microstructure and magnetic properties of C/Co-P and Al2O3/Co-P composite particles prepared by electroless plating / E. A. Denisova [et al.] // J. Appl. Phys. - 2013. - Vol. 113, Is. 17. - Ст. 17A340. - P. DOI 10.1063/1.4800037
   Перевод заглавия: Микроструктура и магнитные свойства композиционных частиц C/Co-P и Al2O3/Co-P, изготовленных методом химического осаждения
Аннотация: The electroless plating is used to synthesize two types of composite powder, such as the activated carbon with pores filled by Co100-XPX particles and the Al2O3 microgranular coated by the shell which consists of Co100-XPX particles with 4 X 18. The magnetic and structural properties of the composite particles are characterized by scanning electron microscopy, X-ray diffraction, and vibrating sample magnetometer. It is found that the average Co(P) particle size in composite powders decreases from 300 nm to 120 nm with an increase in P- content from 4 to 18 at. %. It causes a reduction in coercivity from 300 to 80 Oe for Al2O3/Co(P) powders and from 680 to 150 Oe for C/Co(P) powders. The effects of two methods of immobilization of Co(P) particles on magnetic properties are studied.

nanomagnetics -- rods with gradients of composition -- electroless deposition -- coercivity -- magnetic anisotropy
Аннотация: A comparative study of the magnetic properties of arrays of Co–Ni rods with different composition gradients (smooth or step-like) along the rod axes was carried out. Ordered arrays of Co–Ni nanorods with diameters up to 400 nm and 8 µm length were prepared by electroless plating into a porous nuclear-track-etched polycarbonate membrane. The gradient in Co and Ni composition was confirmed by energy-dispersive X-ray analysis. The variation of Co–Ni contents along the long axis of the rods correlates with the gradient of the magnetization within the rod. Magnetization reversal was studied by analyzing the angular dependence of coercivity and using micromagnetic simulations. For both types of gradient rods, reversal occurs by curling. The local magnetic anisotropy field of rods with a step-type gradient is significantly higher than that for rods with a smooth gradient.

3d-metal alloys -- the approach to saturation magnetization law -- coercivity
Аннотация: The structural and magnetic properties of nanostructured Fe100–xNix-C (0 ˂ x ˂ 100) coatings produced by electroless plating with different carbohydrates as reducing agents have been investigated. The phase-structural state of the films was studied by diffraction and electron microscopy. The Ni concentration ranges of FCC and BCC phases existence in electroless deposited films were determined. The surface morphology, saturation magnetization, local magnetic anisotropy field and coercivities of films are dependent on the iron content and type of reducing agent. The correlation between coercivity Hc and the anisotropy field of the magnetic stochastic domain which were established by correlation magnetometry suggests that the magnitude of Hc is mainly determined by this anisotropy.

Аннотация: Composite materials with Co(P) particles embedded into pores of silica and track etched polycarbonate membranes were fabricated by an electroless reduction. The magnetic and structural properties of the composite materials are characterized by scanning electron microscopy, X-ray diffraction, and vibrating sample magnetometer. The macroscopic and local magnetic anisotropy of the Co(P) particles electroless deposited in the pores of the polycarbonate membrane and silica is studied. The composite materials with linear pores exhibit uniaxial magnetic anisotropy. The easy axis lies along the Co(P) rods, the shape anisotropy dominates over the intrinsic crystalline anisotropy. Information on local anisotropy field and the grain size was obtained from investigation of approach to saturation magnetization law. The local anisotropy field for all the samples depends on P content. For Co(P) rods the local anisotropy value is also determined by nominal pore sizes. It was found that the investigated Co(P) rods is nanocrystalline. The effects of different pores morphology on the MR-spectra characteristics are studied

magnetic anisotropy -- FeCo–C coatings -- electroless deposition -- approach to magnetic saturation law
Аннотация: Fe–Co alloys attracting interest due to their high magnetic induction and Curie temperature, were synthesized by an eco friendly electroless deposition with carbohydrates as reducing agents. It was shown that Fe1–xCox–C composite coatings retain high induction, while demonstrating an unusual behavior of magnetization at low temperatures. It was found that for each coating measured at different temperatures, there is a correlation between the local magnetic anisotropy constant K at a given temperature and the correlation radius of the local easy magnetization axis Rc. The functional type of this correlation is typical for nanoparticles or nanogranules in a composite, which made it possible to estimate the volume and surface magnetic anisotropy constants of metal granules of FeCo–C coatings.

High-induction Fe-Co coating -- Electroless deposition -- Structure -- Magnetic properties -- Eco-friendly synthesis
Аннотация: A facile, low-cost, and green route for synthesis of high-induction Fe-Co coatings was developed. Within this approach, three natural reducing agents have been used for deposition of the metal coatings by electroless plating on dielectric and metallic substrates: arabinogalactan, starch, and sucrose. The Fe-Co alloy coatings with Co content from 0 to 94 at.% are nanocrystalline bcc solid solution with carbon additive no more than 2 at%, and pure Co coatings are of hcp structure. The magnetic properties of bcc-based iron-cobalt alloys have been investigated as a function of the atomic composition. A high-saturation magnetization of about 240 emu/g was obtained for Fe70Co30 alloy films deposited onto copper substrate. The local magnetic anisotropy of FeCo alloys increases with a decrease in iron content for all reducing agents. High magnetization close to those in the bulk Fe-Co alloys implies the prospective applications of synthesized Fe-Co coatings as magnetic shield and magnetic sensors.

Аннотация: Co1−x-Px films (x = 0.02–0.05) deposited on cover glass by electroless plating from aqueous solutions in a continuous magnetic field with the strength of 2.5 kOe are presented. It has been found that in the pH range from 7.2 to 9.3, two special areas can be distinguished, they are characterized by the deposition of films with qualitatively different parameters in them. So, the change of the pH of working solutions from 7.2 to 8.7 causes the increase in the value of the induced magnetic anisotropy constant KU from 2.5 × 105 erg/cm3 to 6 × 105 erg/cm3. If the value of the hydrogen index is still increasing, an uneven drop to 5 × 104 erg/cm3 is observed. In the same way, the coercivity HC changes; at first it grows from 700 Oe to 1.5 kOe, and then it drops to Oe units. The concentration of phosphorus in the range of 7.2 to 8.7 increases linearly from 2 to 3 wt%, and in the range of 8.7 to 9.3, it increases from 3 to 5 wt%. The x-ray diffraction data show that the samples obtained at pH<8.7 are characterized by the presence of the hcp phase of Co (α-Co). The observed reflections of films obtained at pH > 8.7 indicate the fcc-Co (β-Co) with the diffraction peak blurring: the greater the pH value of the samples obtained, the more the diffraction peak blurring. It is shown that the induced magnetic anisotropy in high-coercivity films relates to the modification of the Co lattice. The lattice passes from a distorted fcc to an hcp structure during the growth of crystallites in a magnetic field. The induced magnetic anisotropy appears in films that were obtained in the high pH field due to the ordering of magnetic ions pairs.

Аннотация: We report ferromagnetic and spin-wave resonance measurements on the electroless deposited thin films of Fe-Ni alloy including alloy with invar content. From spin-wave resonance spectrum we defined the dependences of resonance fields on the number of mode. Analysis of this spectrum shows that positions of resonance fields are described by the Kittel dispersion relation. The type and the size of magnetic heterogeneity is estimated by the spin-wave spectroscopy technique. © (2015) Trans Tech Publications, Switzerland.
