Ground-state wave function of the two-dimensional t-J model is found at doping close to half filling. It is shown that the condensation of Cooper pairs (superconducting pairing of mobile holes) and the condensation of spin waves into the spin-liquid state are closely connected. The effective spectrum of S=1 excitations, spin-wave pseudogap \mathrm\ensuremathΔM, magnetic correlation length \ensuremathξM, and static magnetic formfactor SM(q) are calculated. \textcopyright 1996 The American Physical Society.
