Microwave pinning-mode resonances found around integer quantum Hall effects, are a signature of crystallized quasiparticles or holes. Application of in-plane magnetic field to these crystals, increasing the Zeeman energy, has negligible effect on the resonances just below Landau-level filling ν=2, but increases the pinning frequencies near ν=1, particularly for smaller quasiparticle or hole densities. The charge dynamics near ν=1, characteristic of a crystal order, are affected by spin, in a manner consistent with a Skyrme crystal.
微波钉扎模式共振出现在整数量子霍尔效应周围，是准粒子或空穴结晶的特征。对这些晶体施加面内磁场会增加塞曼能，但对朗道能级填充 ν=2 以下的共振几乎没有影响，却会增加 ν=1 附近的钉扎频率，尤其是在较小的准粒子或空穴密度下。在 ν=1 附近，晶体有序特征的电荷动力学受到自旋的影响，这与 Skyrme 晶体一致。
