We find that the temperature dependence of the drag resistivity between two dilute two-dimensional hole systems exhibits an unusual dependence upon spin polarization. Our main observation is that near the apparent metal-insulator transition, the temperature dependence of the drag, given by T α, weakens significantly with the application of a parallel magnetic field (B∥), with a saturating at half its zero field value for B∥ > B*, where B* is the polarization field.
