N2 - Low-energy spin excitations of [Formula presented] were studied by neutron scattering. In [Formula presented], the incommensurate magnetic peaks show a well-defined “spin gap” below [Formula presented]. The magnetic signals at [Formula presented] decrease below [Formula presented] for [Formula presented], also suggesting the gap opening. At lower temperatures, however, the signal increases again, implying a novel in-gap spin state. In [Formula presented], the spin gap vanishes and elastic magnetic peaks appear. These results clarify that doped Zn impurities induce the novel in-gap state, which becomes larger and more static with increasing Zn.
