Abstract: We present a proof-of-principle way to generate nondegenerate multipartite continuous-variable entanglement via atomic spin wave induced by the strong coupling and probe fields in the \ensuremath{\Lambda}-type electromagnetically induced transparency configuration in an atomic ensemble. Quantum correlated or anticorrelated and entangled Stokes and anti-Stokes fields, simultaneously produced through scattering the applied laser fields off the atomic spin wave, can be achieved. This method can, in principle, be extended to flexibly and conveniently create multicolor multipartite entangled narrow-band fields to any desired order with long correlation time, which may find promising applications in quantum information processing and quantum networks.
