Ae. Lobanov et Os. Pavlova, Solutions of the classical equation of motion for a spin in electromagnetic fields, THEOR MATH, 121(3), 1999, pp. 1691-1699
The evolution of a charged particle spin in electromagnetic fields of a spe
cial form is investigated based on the Bargmann-Michel-Telegdi equation. Fo
r some types of nonhomogeneous fields, an exact analytic form of the depend
ence of the spin vector on the four-dimensional velocity of the particle is
found.
