“…Nanomaterials attract a lot of attention from researchers and developers due to their anomalous optical, thermal, electrical, and magnetic properties, and significant differences from their bulky counterparts [1]. Spinel ferrites are a hybrid functional material with the general formula MFe 2 O 4 (M = Mg 2+ , Co 2+ , Mn 2+ , Ni 2+ , Zn 2+ ) [2][3][4]. Ferrites are essential for many recent technological designs of electrical, magnetic, and microwave devices [5][6][7].…”

Nanocomposite films based on spinel ferrite (Mg0.8Zn0.2Fe1.5Al0.5O4) in a PVA matrix were obtained. An increase in the spinel concentration to 10 wt.% caused an avalanche-like rise in roughness due to the formation of nanoparticle agglomerates. The lateral mode of atomic force microscopy (AFM) allowed us to trace the agglomeration dynamics. An unexpected result was that the composite with 6 wt.% of filler had a low friction coefficient in comparison with similar composites due to the successfully combined effects of low roughness and surface energy. The friction coefficient decreased to 0.07 when the friction coefficient of pure PVA was 0.72. A specially developed method for measuring nano-objects’ surface energy using AFM made it possible to explain the anomalous nature of the change in tribological characteristics.

“…Поэтому для МСМ более реалистичным является случай релаксационной зависимости МП вида (38), когда справедливы формулы (39)−(47). Такой вид дисперсии, например, имеют ферриты Zn 1−x Ni x Fe 2 O 4 [16]. После нормировки на величину F 0 = 32π 2 µs −1 µs +1 M 2 0 R 2 зависимости f x = F x /F 0 и f z = F z /F 0 будут являться функциями параметров p, q, a в случае параболического зонда и параметров p, a в случае сферического.…”

The forces acting on a magnetic particle during nonrelativistic motion parallel to the surface of a homogeneous medium with a frequency dispersion of magnetic permeability are considered. General expressions are obtained for the normal (attractive) and lateral (braking) forces acting on a small dipole particle and an extended probe. It is shown that for an arbitrary orientation of the vector of the dipole magnetic moment of the particle, along with the force of attraction and the stopping force, there also appears a velocity-dependent lateral force perpendicular to the velocity vector. The possibility of using the results to study the frequency-dependent magnetic permeability of nanostructured materials and films in the dynamic scanning mode of magnetic force microscopy (MCM) with magnetic probes is discussed. Numerical estimates are given for the magnitude of the expected forces, friction coefficients, and changes in the quality factor of the MFM oscillators in the case of frequency dispersion of relaxation-type magnetic permeability.

Ni substitution effect on the structure, magnetization, resistivity and permeability of zinc ferrites

Abstract: Increase in the spontaneous magnetization up to x < 0.5 is a sequence of appearance of the additional magnetic moment of 2 μB of the Ni2+ cations in tetrahedral positions. For x > 0.5, the moment decreases in octahedral positions and the spontaneous magnetization also decreases.
