Collective Spin Glass State in Nanoscale Particles of Ferrihydrite / S. V. Stolyar, R. N. Yaroslavtsev, V. P. Ladygina [et al.] // Semiconductors. - 2020. - Vol. 54, Is. 12. - P. 1710-1712DOI 10.1134/S1063782620120362. - Cited References: 16. - This work was supported by the Russian Foundation for Basic Research, the Government of the Krasnoyarsk Territory, the Krasnoyarsk Regional Fund for the Support of Scientific and Technical Activities (project no. 19-42-240012 r_a “Magnetic resonance in ferrihydrite nanoparticles: Effects associated with the “core–shell” structure).

Кл.слова (ненормированные):
nanoparticles -- ferrihydrite -- magnetic anisotropy -- magnetic resonance
Аннотация: Ferromagnetic resonance was used to study three types of ferrihydrite nanoparticles: nanoparticles formed as a result of the cultivation of microorganisms Klebsiella oxytoca; chemically prepared ferrihydrite nanoparticles; chemically prepared ferrihydrite nanoparticles doped with Cu. It is established from the ferromagnetic resonance data that the frequency-field dependence (in the temperature range ТP ‹ T ‹ T*) is described by the expression: 2πν/γ ⁼ НR + HA(T = 0)(1 – T/Т*), where γ is the gyromagnetic ratio, HR is the resonance field. The induced anisotropy HA is due to the spin-glass state of the near-surface regions. TP temperature characterizes the energy of the interparticle interaction of nanoparticles.

Аннотация: The effect of magnetic nanoparticles coated with arabinogalactan on the viability of Ehrlich ascites carcinoma (EAC) cells was studied. The nanoparticles were studied by transmission electron microscopy, Mossbauer spectroscopy, IR spectroscopy, and ferromagnetic resonance. A correlation between the proportion of dead EAC cells in suspension and the intensity of the EPR signal of dinitrosyl iron complexes was found. This result may be due to the presence of NO molecules.

Аннотация: Using minor hysteresis loops in the Stoner-Wohlfarth model allows describing the experimental behavior of the coercive force of minor hysteresis loops in ferrihydrite nanoparticles with a change in the field amplitude. The description allows estimating the parameters of the distribution of the magnetic anisotropy field in nanoparticles. The best agreement of the anisotropy fields estimated by different approaches is achieved for the assumption of uniaxial anisotropy in ferrihydrite nanoparticles.

Кл.слова (ненормированные):
Magnetite -- Nanoparticles -- Magnetic anisotropy
Аннотация: Square plate shaped magnetite nanocrystals have been synthesized by chemical precipitation from solution using arabinogalactan. A high crystal quality was observed in the plate plane while, across the plate, there is some stratification. The magnetic hysteresis in such particles is determined by the bulk magnetocrystalline anisotropy, plate shape anisotropy, and surface magnetic anisotropy. It is shown using the micromagnetic simulation that the ferromagnetic square nanoplates exhibit the extraordinary magnetization switching anisotropy, which should be taken into account for understanding the hysteretic properties of the particles.
