Abstract

In a method of testing a multilayer structure containing a magnetic layer, one or more network parameters are measured of a waveguide that is electromagnetically coupled with the multilayer structure as a function of frequency and as a function of a magnetic field applied to the multilayer structure during the measuring of the network parameters. Based on the measured one or more network parameters, at least one magnetic property of the magnetic layer of the multilayer structure is determined. The network parameters in some embodiments are S-parameters. The at least one magnetic property may include an effective anisotropy field of the magnetic layer and/or a damping constant of the magnetic layer.
