Accelerated mechanical alloying of mutually insoluble metals: Co-Cu system / R. S. Iskhakov [et al.] // Tech. Phys. Lett. - 2004. - Vol. 30, Is. 1. - P. 60-63, DOI 10.1134/1.1646717. - Cited References: 11 . - ISSN 1063-7850

Аннотация: We propose a new method for accelerating the process of mechanical alloying in the Co-Cu system possessing positive enthalpy of mixing and exhibiting no mutual solubility of components under equilibrium conditions. For this purpose, highly disperse powders of composite particles representing a Co-P amorphous alloy core covered with a nanocrystalline copper shell were prepared by chemical deposition. These composite powders were mechanically alloyed by processing in a ball mill. Investigation of the atomic structure and magnetic properties of the composite powders upon milling showed that the formation of supersaturated Co-Cu solid solutions under such conditions requires a much shorter milling time as compared to that for the conventional mechanical alloying processes.

Advanced characterization of FeNi-based films for the development of magnetic field sensors with tailored functional parameters / S. V. Komogortsev, I. G. Vazhenina, S. A. Kleshnina [et al.] // Sensors. - 2022. - Vol. 22, Is. 9. - Ст. 3324, DOI 10.3390/s22093324. - Cited References: 35. - This research was funded by the Russian Science Foundation (RSF), project no. 22-29-00980, https://rscf.ru/en/project/22-29-00980/ (accessed on 20 March 2022) . - ISSN 1424-8220

Аннотация: Magnetometry and ferromagnetic resonance are used to quantitatively study magnetic anisotropy with an easy axis both in the film plane and perpendicular to it. In the study of single-layer and multilayer permalloy films, it is demonstrated that these methods make it possible not only to investigate the average field of perpendicular and in-plane anisotropy, but also to characterize their inhomogeneity. It is shown that the quantitative data from direct integral and local measurements of magnetic anisotropy are consistent with the direct and indirect estimates based on processing of the magnetization curves. The possibility of estimating the perpendicular magnetic anisotropy constant from the width of stripe domains in a film in the transcritical state is demonstrated. The average in-plane magnetic anisotropy field of permalloy films prepared by magnetron sputtering onto a Corning glass is almost unchanged with the thickness of a single-layer film. The inhomogeneity of the perpendicular anisotropy field for a 500 nm film is greater than that for a 100 nm film, and for a multilayer film with a total permalloy thickness of 500 nm, it is greater than that for a homogeneous film of the same thickness.

Analysis of phase composition of Co-P alloy powders using magnetometric data / L. A. Chekanova [et al.] // Phys. Metals & Metallogr. - 2013. - Vol. 114. Is. 2. - P. 122-128DOI 10.1134/S0031918X1302004X
Аннотация: A new method for the quantitative estimate of the phase composition of a multiphase ferromagnetic alloy is suggested that is based on measuring the temperature and field dependences of the magnetization. The phase composition of ultrafine Co-P powders is characterized. Phase diagrams of nonequilibrium Co-P solid solutions are constructed on particle size, i.e., the phosphorus concentration coordinates.

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.

Nanoparticles -- Carbon -- Nickel
Аннотация: The nickel particles with the mean size about 10-20 nm coated with carbon were extracted by the treatment of the carbon condensate with nitric and hydrochloric acids. The initial carbon condensate containing nickel nanoparticles with a graphite conversion was synthesized in the high-frequency carbon-helium arc plasma at ambient pressure with the nickel nanoparticles as a catalyst. The nickel content in the nanoparticles was 84.6 wt %. Magnetic properties of the nanoparticles are characterized by the high hysteresis and thermal stability. The sample of compacted nanoparticles is characterized by electrical resistance much higher than it in of compacted initial condensate.

Аннотация: An experimental determination (both direct and indirect) of the characteristics of the magnetic microstructure, namely, the ferromagnetic correlation radius R-f and the rms fluctuation of the mean anisotropy D-1/2H-a, is performed for amorphous and nanocrystalline ferromagnets with a random anisotropy characterized by the quantities R-c and (DHa)-H-1/2, respectively. The magnetization curves of amorphous and nanocrystalline ferromagnets are found to exhibit a dependence on H that is caused by the alignment of the magnetizations of individual magnetic blocks with the field.
