Revealing the ultrafast light-to-matter energy conversion before heat diffusion in a layered Dirac semimetal
Y. Ishida, H. Masuda, H. Sakai +2
There is still no general consensus on how one can describe the out-of-equilibrium phenomena in matter induced by an ultrashort light pulse. We investigate the pulse-induced dynami…
Femtosecond core level photoemision spectroscopy on 1T-TaS2 using 60 eV laser source
K. Ishizaka, T. Kiss, T. Yamamoto +11
Time-resolved photoelectron spectroscopy (trPES) can directly detect transient electronic structure, thus bringing out its promising potential to clarify nonequilibrium processes a…
Combining photoemission and optical spectroscopies for reliable valence determination in YbS and Yb metal
M. Matsunami, A. Chainani, M. Taguchi +13
Hard x-ray photoemission and optical spectroscopies have been performed on YbS and Yb metal to determine the precise -electron occupation. A comparison of the photoemission spec…
Hybridization between the conduction band and 3d orbitals in the oxide-based diluted magnetic semiconductor InVO
M. Kobayashi, Y. Ishida, J. I. Hwang +11
The electronic structure of InVO () has been investigated using photoemission spectroscopy (PES) and x-ray absorption spectroscopy (XAS). The V core-le…
Effect of Reducing Atmosphere on the Magnetism of Zn1-xCoxO Nanoparticles
M. Naeem, S. K. Hasanain, M. Kobayashi +4
We report the crystal structure and magnetic properties of Zn1-xCoxO nanoparticles synthesized by heating metal acetates in organic solvent. The nanoparticles were crystallized in…
Characterization of Magnetic Components in the Diluted Magnetic Semiconductor ZnCoO by X-ray Magnetic Circular Dichroism
M. Kobayashi, Y. Ishida, J. l. Hwang +12
We report on the results of x-ray absorption (XAS), x-ray magnetic circular dichroism (XMCD), and photoemission experiments on {\it n}-type ZnCoO () thin film,…
