I will report recent progress on vapor cell atomic magnetometers and co-magnetometers. The first part of the talk describes a Rb scalar gradiometer using two multipass optical cells. We use a pump-probe measurement scheme to suppress spin-exchange relaxation and reach sub-femtotesla magnetic field sensitivity. It approaches, for the first time, the fundamental limit set by Rb-Rb collisions. The second part of the talk reports recent progress in the development of a new co-magnetometer using He-3 and Xe-129 nuclear spins.
