Figure 1From: Impedance of nanometer thickness ferromagnetic Co40Fe40B20 films Two Co 40 Fe 40 B 20 film samples. L is the length and w the width. i ac is the ac current sent through each sample. is the saturation magnetization and is the deposition field. and are the in-plane spin-wave wave vectors. (a) The ||L case and (b) the ||w case.Back to article page
