The incommensurate peaks at 9 meV, which in zero field were previously shown to sharpen in q on cooling below Tc T. E. Mason et al., Phys. Rev. Lett. 77, 1604 (1996), are found to broaden in q when a field of 10 T is applied. The applied field also causes scattered intensity to shift into the spin gap. We point out that the response at 9 meV, though occurring at incommensurate wave vectors, is comparable to the commensurate magnetic resonance observed at higher energies in other cuprate superconductors.
