我们演示了通过超导共面波导谐振器实现两个独立坡莫合金条中铁磁共振的相干耦合。两个条放置在谐振器顶部，各自长轴之间的夹角为50°。这种对准使我们能够通过在样品平面内旋转外部偏置磁场，利用形状各向异性分别调节它们的铁磁共振频率。两个独立的铁磁体均与微波谐振器呈现强耦合。该方法避免了使用独立的局部偏置线圈，便于将类似实验集成到平面器件架构中。
英文摘要
We demonstrate coherent coupling of ferromagnetic resonance in two individual permalloy stripes via a superconducting coplanar waveguide resonator. The two stripes are placed on top of the resonator with an angle of 50$^{\circ}$ between their respective long axes. This alignment enables us to separately tune their ferromagnetic resonance frequency by exploiting their shape anisotropy by simply rotating the external bias magnetic field in the sample plane. Both individual ferromagnets exhibit strong coupling with the microwave resonator. This method avoids the use of local individual bias coils and facilitates the integration of similar experiments into planar device infrastructures.
