摘要：

Phase diagram of the S = 1/2, J(1)-J(2)-J(3) Heisenberg model on the square lattice with ferromagnetic 1(st) neighbor and antiferromagnetic 2(nd) and 3(rd) neighbor interactions is studied by means of exact diagonalization and spin wave calculations. Quantum fluctuations are shown to induce phases that are not present classically and a shift in the wave vector of the spiral phases. Results are compared with recent experimental data.
