Dependence of electronic properties of epitaxial few-layer graphene on the number of layers investigated by photoelectron emission microscopy
TL;DR: In this paper, the electronic properties of epitaxial few-layer graphene grown on 6H-SiC (0001) were investigated using spectroscopic photoemission and low-energy electron microscopy.
Journal ArticleDOI
Performance of a very high resolution soft x-ray beamline BL25SU with a twin-helical undulator at SPring-8
Yuichi Saitoh,Hiroaki Kimura,Y. Suzuki,T. Nakatani,Tomohiro Matsushita,Takayuki Muro,Tsuneaki Miyahara,Masami Fujisawa,Kazuo Soda,Shigenori Ueda,Hideyuki Harada,Masato Kotsugi,Akira Sekiyama,Shigemasa Suga +13 more
TL;DR: In this paper, the authors reported on the excellent performance of a newly constructed soft x-ray helical undulator beamline BL25SU of SPring-8 for photon energies 500-1800 eV.
Journal ArticleDOI
Tuning the magnetic coupling across ultrathin antiferromagnetic films by controlling atomic-scale roughness
Wolfgang Kuch,Wolfgang Kuch,Li Chelaru,Francesco Offi,Jing Wang,Masato Kotsugi,Jürgen Kirschner +6 more
TL;DR: Atomic-level control of the interface morphology is achieved by systematically varying the thicknesses of the bottom ferromagnetic and the antiferromagnetic layer, and it is found that the magnetic coupling across the interface is mediated by step edges of single-atom height, whereas atomically flat areas do not contribute.
Journal ArticleDOI
Inhomogeneous chemical states in resistance-switching devices with a planar-type Pt/CuO/Pt structure
R. Yasuhara,Kohei Fujiwara,Koji Horiba,Hiroshi Kumigashira,Masato Kotsugi,Masaharu Oshima,Hidenori Takagi +6 more
TL;DR: In this paper, the spatial distribution of chemical states in resistance-switching devices with a planar-type Pt/CuO/Pt structure has been studied by photoemission electron microscopy.
Journal ArticleDOI
Fe-Ni composition dependence of magnetic anisotropy in artificially fabricated L10-ordered FeNi films
Takayuki Kojima,Misako Ogiwara,Masaki Mizuguchi,Masato Kotsugi,Tomoyuki Koganezawa,Takumi Ohtsuki,Taka Yuki Tashiro,Koki Takanashi +7 more
TL;DR: The large Ms and Ku of Fe60Ni40 indicate that Fe-rich L10-FeNi is promising as a rare-earth-free permanent magnet.
