Such devices can exhibit different types of coupling between magnetic layers, such as: exchange coupling and spin-current mediated coupling. We used the technique of x-ray detected ferromagnetic resonance (XFMR) to study the dynamics of a Co\/MgO\/Permalloy magnetic tunnel junction (MTJ). The experimental results were quantitatively compared to the Landau-Lifshitz-Gilbert-Slonczewski model where an in-depth statistical analysis based on a likelihood ratio test was employed to determine the presence of spin-current mediated coupling between the two magnetic layers<br \/>\n\u0141.Gladczuk et al. , Phys.
