Determination of the exchange constant of Tb(0.3)Dy(0.7)Fe(2) by broadband ferromagnetic resonance spectroscopy

We present measurements of the exchange stiffness D and the exchange constant A of a sputtered 80 nm Tb(0.3)Dy(0.7)Fe(2) film. Using a broadband ferromagnetic resonance setup in a wide frequency range from 10 GHz to 50 GHz, multiple perpendicular standing spin-wave resonances were observed with the...
