Beschreibung:
<jats:p>Ferrimagnetic resonance within the bubble layer is used to couple two microwave transmission lines. If a bubble is switched into the coupling region which is comparable in size with a bubble domain, the transmitted microwave signal changes. For a 5-μm bubble a Zero/One ratio of 6:1 has been obtained. It is also possible to influence the resonance transmission in a reference layer adjacent to the bubble layer by the magnetic stray field of a bubble. At high power levels a nonlinear interaction between the microwaves and the magnetic domains is observed which can be used for bubble generation.</jats:p>
