Orbital Polarization in Itinerant Magnets
I. V. Solovyev
We propose a parameter-free scheme of calculation of the orbital polarization (OP) in metals, which starts with the strong-coupling limit for the screened Coulomb interactions in t…
New Misfit-Layered Cobalt Oxide (CaOH)1.14CoO2
M. Shizuya, M. Isobe, Y. Baba +6
We found a new cobalt oxide (CaOH)1.14CoO2 by utilizing the high-pressure technique. X-ray and electron diffraction studies revealed that the compound has layer structure which con…
Structure of Metastable States in Phase Transitions with High-Spin Low-Spin Degree of Freedom
Seiji Miyashita, Yusuke Konishi, Hiroko Tokoro +3
Difference of degeneracy of the low-spin (LS) and high-spin (HS) states causes interesting entropy effects on spin-crossover phase transitions and charge transfer phase transitions…
Superconductivity in Polycrystalline Diamond Thin Films
Yoshihiko Takano, Masanori Nagao, Tomohiro Takenouchi +4
Superconductivity was discovered in heavily boron-doped diamond thin films deposited by the microwave plasma assisted chemical vapor deposition (MPCVD) method. Advantages of the MP…
Theoretical determination of the necessary conditions for the formation of ZnO nanorings and nanohelices
Z. C. Tu, Q. X. Li, X. Hu
The formation of ZnO nanorings and nanohelices with large polar surfaces observed in experiments [Nano Lett. 3, 1625 (2003); J. Am. Chem. Soc. 126, 6703 (2004)] is shown to be a re…
Robust Half-Metallic Character and Large Oxygen Magnetism in a Perovskite Cuprate
Xiangang Wan, Masanori Kohno, Xiao Hu
The new perovskite cuprate material SrCaReCuO, which behaves ferrimagnetically and shows an unusually high Curie temperature ( 440 K), is found f…
