  We present a protocol for the teleportation of the quantum state of a pulse
of light onto the collective spin state of an atomic ensemble. The entangled
state of light and atoms employed as a resource in this protocol is created by
probing the collective atomic spin, Larmor precessing in an external magnetic
field, off resonantly with a coherent pulse of light. We take here for the
first time full account of the effects of Larmor precession and show that it
gives rise to a qualitatively new type of multimode entangled state of light
and atoms. The protocol is shown to be robust against the dominating sources of
noise and can be implemented with an atomic ensemble at room temperature
interacting with free space light. We also provide a scheme to perform the
readout of the Larmor precessing spin state enabling the verification of
successful teleportation as well as the creation of spin squeezing.
