(abstract)

We report experimental and theoretical evidence that Rb2Cu2Mo3O12 has a nonmagnetic tetramer ground state of a two-leg ladder comprising　antiferromagnetically coupled frustrated spin- 1/2 chains and exhibits a Haldane spin gap of emergent spin-1 pairs. Three spin excitations split from the spin-1 triplet by a Dzyaloshinskii-Moriya interaction are identified in inelastic neutron-scattering and electron spin resonance spectra. A tiny magnetic field generates ferroelectricity without closing the spin gap, indicating a unique class of ferroelectricity induced by a vector spin chirality order.
