摘要: An experimental and theoretical study is presented of the normal magnetic modes in spiral ferromagnetic structures. The bilayer system studied consists Fe layers (25, 50, 100, 200 A thick) that are exchange coupled to thick SmCo films have ≈200 kOe anisotropies. spiral—induced by an external field applied opposite direction magnetized film—results a structure similar encountered Bloch domain wall. magnetization dependence magnons various explained model.
