  A scheme is described in which the light gravitino in low energy SUSY
breaking models mixes with neutrinos. The mixing between gravitino and
neutrinos arises through the standard model symmetry breaking and an R-parity
and lepton number violating bilinear term in the superpotential. It is shown
that mixings compatible with the neutrino experiments can be obtained within
the cosmological bound on the bilinear term set by the baryon asymmetry of the
universe.
