Resumen:
The magnetic properties of Fe/Zn/Fe trilayers have been studied by ferromagnetic resonance and magnetizationmeasurements. These measurements have been used to investigate the magnetic anisotropy of the iron layers and themagnetic coupling across the semiconductor spacer. The angular dependence of the resonance spectra has beenmeasured in-plane and out-of-plane in order to deduce magnetic anisotropy constants of the samples. Experimentaldata were fitted by using an energy-density expression that includes bulk cubic anisotropy, growth-induced uniaxial inplaneanisotropy and perpendicular-surface anisotropy terms. A small ferromagnetic coupling is observed in thetrilayers with spacer thickness up to 50 (A:
