测量了单晶UBe 13的表面阻抗测量Z-S，其中Z-S由表面电阻R-S和表面电抗X-S组成。R-S表现出反常的场依赖关系，在H*附近有一个明显的驼峰，几乎等于0.6Hc2。这一行为表明，在H*附近发生了强烈的涡钉扎现象。
Surface impedance measurements Z s, where Z s consists of surface resistance R s and surface reactance X s, were carried out for a single crystal UBe 13. R s exhibits unusual field dependence with a significant hump around the H*, which is nearly equal to 0.6H c2. This behavior indicates that the strong vortex pinning occurs around H*.
