X線磁気円偏光発光（XMCPE）は一言でいえば、「強磁性体からの特性発光 X 線が円偏極する現象」である。遷移金属の特性X線といえば、Cu や Mo の Kα 線（2p→1s 遷移）が結晶構造解析など

これまでのX線磁気円偏光発光（XMCPE）の実験および理論研究はすべてFe(BCC)に対してのみ行われており、物質依存性は調べられていない。そこで本研究では、Feと同じ3d遷移金属であるCo(HC

In this study, we calculate x-ray magnetic circularly polarized emission (XMCPE) spectra at Kα transition for ferromagnetic 3d transition metals (TMs), specifically Fe(bcc), Ni(fcc), and Co(hcp). We obtain XMCPE spectra which agree well with the exp

We propose sum rules of x-ray magnetic circularly polarized emission (XMCPE) at $L$ edges for $3d$ transition metals. By making use of combinations of incident and emitted photon helicities, $z$-component expectation values of spin, orbital, magnetic

This study provides a theoretical method to calculate x-ray magnetic circularly polarized emission spectra at the K${}_{\ensuremath{\alpha}}$ transitions in transition-metal ferromagnets. The method is applied to metallic iron. It reproduces the obse

Eutectic Sr2RuO4-Ru samples show an onset of inhomogeneous superconductivity at around 3 K, which is above the bulk transition of Sr2RuO4 (SRO) with Tc≈1.5 K. This superconducting state nucleates most likely as a filamentary state at the interface

We use the Ginzburg-Landau theory for a chiral $p$-wave superconductor to describe the filamentary superconducting phase nucleating at temperatures higher than the bulk transition temperature near the interfaces between Ru metal and ${\mathrm{Sr}}_{2

The control and detection of crystallographic chirality is an important and challenging scientific problem. Chirality has wide ranging implications from medical physics to cosmology including an intimate but subtle connection in magnetic systems, for

We develop a theoretical method to calculate x-ray magnetic circularly polarized emission (XMCPE) spectra for itinerant ferromagnets, in particular, Kα emission for transition metals. The effects of electron excitations in the d bands are treated by
