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.

Аннотация: The deposition kinetics, structure and magnetic properties of electroless deposited films Ni-P were investigated depending on the amount of sodium hypophosphite in the electroless bath. It was found that the film deposition rate is linear and unambiguously varies with the hypophosphite content from 2 to 13 g/l and from 23 to 25 g/l. The deposition rate varies widely in the hypophosphite concentration range from 13 to 23 g/l. The films are composed of amorphous Ni-P phase and fcc Ni-P solid solution with phosphorus content from 1 to 4 at.% P according to X-ray diffraction. The partial amount of amorphous phase is increased with concentration of sodium hypophosphite. The ferromagnetic resonance field is independent on the concentration of sodium hypophosphite, which assumes to be result from the laminated allocation of the amorphous and fcc phases in the film. © (2014) Trans Tech Publications, Switzerland.

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

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.

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.

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.

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: 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: A porous polymer loaded with segmented nanorods of magnetic metal is very promising for the design of novel microwave devices. Arrays of bi-segmented Ni/Co and core-shell Ni@Co rods were prepared by electroless deposition into porous of polycarbonate track etched membrane. An intrinsic effective magnetic field of the magnetic composite nanorods aligned in the nonmagnetic template was studied by magnetization curves and ferromagnetic resonance. The effect of the interface boundaries for two types of bi-segmented rods with coaxial and along-axis Co/Ni segmentation to effective field was established.

Аннотация: In this work, we investigated the ferromagnetic resonance spectra of metal/carbon composite coatings. FeC and NiC coatings were synthesized by electroless deposition using polysaccharide arabinogalactan. An analysis of the angular dependences of the resonance field showed that the coatings consist of three magnetic phases separated by a nonmagnetic phase of carbon.

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.

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.
