35. The frequency of the steady-state oscillations as measured by the SA only changed by a small amount (from 15.5 to (Equation presented)) when the applied field was reversed, while its intensity increased to (Equation presented) over noise.
36. The analysis was performed only on the current-dependent, and not on the field-dependent, measurements, because if one modifies the external field, the whole SW dispersion curve would be modified for every given value of the field. This does not happen in the current-dependent measurements. As a consequence, it would be much more difficult to extract useful information from such a complex analysis.
