Abstract
Interlayer magnetic coupling in multilayered systems remains a central issue in the understanding and designing of functional low-dimensional magnetic heterostructures. In this work, we investigate the magnetic coupling between magnetostrictive layers with opposite magnetostriction constants that remains unaffected by the introduction of a nonmagnetic Cu spacer layer. We present in-plane hysteresis loops and ferromagnetic resonance spectra and show that angle-resolved ferromagnetic resonance experiments demonstrate a single resonance at all orientations. We, therefore, conclude that there is a magnetoelastically induced coupling between the two magnetic films despite the presence of a nonmagnetic Cu layer between them.
