  This paper contains suggestions for experiments with usage of the Spin
Physics Detector (SPD) at the first stage of the SPD NICA Programme developing
at JINR. Double polarized pp-, dd- and pd- collisions at c.m.s. NN energies of
3.4-10 GeV, which will be accessible at the initial stage of experiments, allow
one to study spin dependence of the NN interaction, search for multiquark
states at double strangeness, charm and beauty thresholds, study the
short-range structure of the deuteron. Double polarized pd scattering offer a
possibility to test the Standard Model through the search for T-invariance
violation.
