Approximate explicit formulas for Stoner-Wohlfarth hysteresis loops
Savin Vladimir P., Koksharov Yury A
Approximate explicit formulas for the hysteresis loops in the Stoner-Wohlfarth model are derived. We consider the hysteresis loops both for a single particle with a fixed easy-axis…
Enhanced coercive force of nanoparticles of special morphology in the Stoner-Wohlfarth model
Vladimir P. Savin, Yury A. Koksharov
We have found an unusual effect of increasing the coercive force in the Stoner-Wohlfarth model applied to magnetic nanoparticles of a special morphology. The particles consist of a…
Screening effect of a magnetically soft shell of single-domain ferromagnetic nanoparticles
Vladimir P. Savin, Yury A. Koksharov
The possible manifestations of magnetic screening effects were theoretically investigated for a particle with a ferromagnetic single-domain core and a magnetically soft shell. The…
Electrostatic repulsion between a uncharged or slightly charged conductor and a point charge
V. P. Savin, Yu. A. Koksharov
A counterintuitive effect of a repulsion between uncharged and charged conductors is considered. Our numerical calculations prove this effect for various axially symmetric systems…
