We report on the study of epitaxial Fe/Cr trilayers with a Cr thickness of 8 nm grown at different temperatures. We show that it is possible to produce systems that exhibit interlayer exchange coupling above room temperature, while being uncoupled at lower temperatures. Through perturbed angular correlation measurements, this macroscopic effect is identified as a direct result of the growth induced characteristics of the antiferromagnetic spin density wave ordering in the Cr spacer.
