Major hysteresis loop (continuous line) compared with the demagnetization remanence curve (symbols) measured with the field applied parallel to the wires in the (a) CoFe and (b) NiFe samples. Different remanent states are generated from FORC (dashed lines) with different return fields .
FMR spectra for the CoFe NWs for different nonsaturated magnetic states obtained with a of (a) −1.1 kOe and (b) −2.0 kOe and the spectra measured at intermediate fields between and zero field, dotted lines are just a guide for the eye.
Zero field FMR spectra for different remanent states measured on the CoFe sample. The dotted line is a guide for the eye.
(a) Measured (filled symbols) and calculated (continuous line) as a function of for the CoFe sample, and (b) measured (symbols) and calculated (continuous line) for in units of as a function of for both the CoFe (filled symbols) and NiFe (open symbols) samples.
