Abstract :
Ferromagnetic resonance measurements were carried out on amorphous ribbons of composition Co/sub 66/Fe/sub 4/B/sub 12/Si/sub 13/Nb/sub 4/Cu/sub 1/ prepared by melt spinning. The field modulated power absorption (dP/dH) was measured as a function of DC magnetic field (H) on strips 2 mm long, in an Electron Paramagnetic Resonance (EPR) spectrometer at X band (9.4 GHz) and Q Band (35 GHz). All spectra were taken at room temperature, under DC magnetic fields up to 10 KG for band X and 20 KG for band Q.
