abstract = {{The "frozen spin" method is based on the fact that at a certain parameters of the ring, the particle spin rotates with the frequency of the momentum, creating conditions for the continuous growth of the electric dipole moment signal. Since a straightforward implementation of the frozen spin regime at NICA is not possible, we suggest an alternative quasi-frozen spin approach concept. In this new regime, the spin oscillates about particle orbit with the spin phase advance pi*gamma*G/2, locally recovering the longitudinal orientation at the location of the electric-magnetic Wien filters in the straight sections. In the case of deuterons, thanks to the small magnetic anomaly G, the spin continuously oscillates relative to the direction of the momentum with a small amplitude of a few degrees and the expected EDM effect is reduced only by a few percent. In this paper, we study the spin-orbital motion with the aim of using the NICA collider to measure the EDM. We also comment on the potential of NICA as an axion antenna in both the quasi-frozen spin regime and beyond.}},
