Аннотация: The ground state of two-dimensional Heisenberg spin-1/2 antiferromagnet (AF) with the spin-phonon coupling is studied by the quantum Monte Carlo method. The magnetic moment per site, mean-square vibration of ion, phase diagram of AF long range order-quantum spin. liquid are simulated. The spin-phonon coupling is estimated for R2CuO4, R = Gd, Eu.
