Efficient dynamic magnetization measurement in a Py/Ru/Py trilayer

It has previously been shown that the quantity called the efficient dynamic magnetization, is a powerful tool for characterizing magnetic layers dedicated to microwave applications. It correlates the imaginary part of permeability and the magnetization distribution. This paper presents microwave permeability spectra of a Py/Ru/Py trilayer, which have been measured in the layer plane under an external magnetic static field (HDC) using a single coil cell. The efficient dynamic magnetization versus HDC was found to exhibit a significant decrease for 0
