报道了埋藏磁畴的体敏显微测量。利用硬x射线下的一种新的磁光效应，即x射线磁圆极化发射（XMCPE），可以清楚地观察到晶粒取向（GO）电钢片的内部横向畴。这使得横向区域的横向形状可以成功地可视化。此外，我们还讨论了在几对入射角和出射角进行测量的表面下补充畴的磁畴结构。
Bulk-sensitive microscopic measurements of buried magnetic domains are reported. Utilizing a new magneto-optical effect in the hard X-ray regime, referred to as X-ray magnetic circularly polarized emission (XMCPE), the internal transverse domains in a grain-oriented (GO) electrical steel sheet are unambiguously observed. This allows the lateral shapes of the transverse domains to be successfully visualized. In addition, we discuss the magnetic domain structure of the supplementary domains below the surface from measurements performed at several pairs of incident and exit angles.
