  "abstract": "Recent measurements by the STAR collaboration have demonstrated that spin correlations of $Λ\\barΛ$ pairs provide sensitivity to the spin structure of $s\\bar{s}$ pairs and to spin transfer during hadronization.These results, together with recent CMS measurements at higher energies, open a new avenue for studying spin dynamics in the transition from partons to hadrons. A feasibility study of spin-spin correlations in $Λ\\barΛ$ pairs at the SPD experiment at NICA is presented for $pp$ and $dd$ collisions at $\\sqrt{s_{NN}}\\leq27$~GeV. The expected correlation $P_{Λ\\barΛ}$ is estimated within the SU(6) and Burkardt--Jaffe models for a spin-triplet $s\\bar{s}$ pair. The kinematic properties of the process are analysed, and the suitability of the detector for such measurements is evaluated using a full simulation. The SPD experiment provides an opportunity to investigate the relative contributions of non-perturbative and perturbative $s\\bar{s}$-production mechanisms and, with polarized beams, to study the role of initial-state polarization in spin-dependent partonic dynamics.",
