DONKIN'S DIFFERENTIAL OPERATORS FOR HOMOGENEOUS HARMONIC FUNCTIONS
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019 The work continues the study of Donkin operators for homogeneous harmonic functions. Previously, a basic list of such first-order operators for three-dimensional harmonic functions was obtained.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Reliable operation of high‐performance magnetostrictive devices, composed of the giant magnetostrictive material (GMM), that is, the TbDyFe alloy, critically depends on an optimally tailored bias magnetic field. Sufficient intensity and uniformity are essential to induce the ideal initial strain in the GMM, enabling peak reciprocating output ...

GENERALIZATION OF THE THOMSON FORMULA FOR HOMOGENEOUS HARMONIC FUNCTIONS
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019 It is shown that the Thomson formula for three-dimensional harmonic homogeneous functions can be generalized if, instead of purely algebraic linear expressions, one uses a linear algebraic form with the participation of the first order partial ...

Magnetostatic field noise near metallic surfaces [PDF]
The European Physical Journal D, 2005 We develop an effective low-frequency theory of the electromagnetic field in equilibrium with thermal objects. The aim is to compute thermal magnetic noise spectra close to metallic microstructures. We focus on the limit where the material response is characterized by the electric conductivity.

Small Science, Volume 6, Issue 3, March 2026.Core–shell alloy‐based BaTiO3/Au–Cu–Co–Ni vertically aligned nanocomposites exhibit tunable nanopillar morphologies governed by interfacial energetics. A temperature–time–transformation diagram predicts nanopillar evolution, while structure–property relationships link morphology with controllable optical anisotropy, hyperbolic dispersion, magnetic ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Marine sediments contain magnetic mineral particles of detrital, biogenic and authigenic origin that record changes in the direction and intensity of the geomagnetic field over geological time. Previous studies have demonstrated that the recording efficiencies of detrital and biogenic magnetite differ.
