A nanometer sized solid solution of NiO and Al2O3 was synthesized by calcination of Ni–Al layered double hydroxides (LDHs). The crystal structure of the obtained compound was determined by XRD and XAFS analyses: Ni2+ and Al3+ ions are located at th

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

Ultrafast excitation of photocatalytically active BiVO4 was characterized by femto- and picosecond transient X-ray absorption fine structure spectroscopy. An initial photoexcited state (≪500 fs) changed to a metastable state accompanied by a struct
