Figure 19
Simulated two-dimensional plots of the normalized reflectivity with opposite helicities of circular polarization during the hysteresis loop from a semi-infinite film of Py without a Pt capping layer or an Si substrate. The field is perpendicular to the scattering plane. The magnetic field is plotted against the sample angle (theta), with values of normalized magnetic reflectivity represented by the colour map. The direction of changing field is indicated by the arrows. |
