Abstract
We have studied the magnetic coupling between the planes in the antiferromagnetic (AF) phase of Sr- and Zn-doped by analyzing the spin-flip transition in the magnetization curves. We find that the interlayer coupling plays a key role in the suppression of the AF phase, and that only mobile holes cause a strong frustration of the interlayer coupling. Depending on the hole mobility, samples with identical Néel temperature can have a very different interlayer coupling.
