    • The resistance of the samples was measured using a four-probe low-frequency ac lock-in technique with spring-loaded pressure contacts. All the magnetoresistance data presented in this paper were measured at 4.5 K. The saturation magnetoresistance Δ R / R is defined as the ratio of the difference between the peak in resistance of the sample at low field and the resistance at high field divided by the value at high field. For samples with thick spacer layers of Cr or Ru the peak of the resistance curve at low fields was shifted from zero field and displayed hysteresis. Magnetization data were measured using vibration sample and SQUID magnetometry. The saturation field Hs was defined as the field at which the resistance or magnetization curve first deviates from the high-field slope.

    • Note that while data are included in Fig. 3 for a Ru layer thickness of 1 Å we assume that at this thickness the Ru layer is discontinuous so that the Co layers are directly exchange coupled.
