CPW – coplanar waveguide External magnetic field Magnetic field lines Magnetic field lines Electric field lines Electric field lines Simulated current Homogenous current I. Neudecker et al. JMMM 307 (2006) 148–156

Channelized Coplanar Waveguide The vias are acting as a microwave wall The other determining factor in the high frequency performance of the vias is the spacing between the rows of the vias. The wider the spacing, the lower the cutoff frequency and the closer the spacing the higher the cutoff frequency. http://mpd.southwestmicrowave.com/pdf/Launch_Report.pdf

Summary We are able to characterize magnetically samples (effective fields, anisotropy, damping parameter) We are able to characterize structure of the sample (film thickness, sublayer thickness, chemical composition)

Thank you for your attention! From our data, both F/AF coupling effects, rotatable and unidirectional anisotropy, can be interpreted as unstable AF grain magnetization, just differing by deviating relaxation times. A continuous transition from rotatable to dominating unidirectional anisotropy is observed. 20
