  In this paper relativistic-invariant phenomenological Lagrangians of
interaction between spin-1 particles and electromagnetic field were obtained in
the Duffin-Kemmer-Petiau formalism on the basis of the covariant model that
takes into account both spin polarizabilities and gyrations of the
above-mentioned particles. It was shown that in the suggested covariant model
with regard to the crossing symmetry, spatial parity and gauge invariance
conservation laws, definite spin polarizabilities and gyrations of spin-1
particles contribute to the expansion of Compton scattering amplitude, starting
from the corresponding orders on energy of pfotons that is in the agreement
with low-energy theorems for that process.
