## Abstract

The fundamentals of precessing ball solitons (PBS) arising as a result of the energy fluctuations at the first-order phase transition induced by a magnetic field in ferromagnets with uniaxial anisotropy are presented. When external magnetic field is anti-parallel to the magnetization direction of the crystal, PBS states are possible in a wide range of amplitudes and energies, including the positive and negative energy relative to an initial condition. PBS are born with the greatest probability at near-zero energy, i.e. near the bifurcation point. Evolution of the PBS, at which they transform into macroscopic domains of a new magnetic phase or into quasi-equilibrium solitonic state, is analyzed.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
