Effect of GGA on the half-metallicity of the itinerant ferromagnet CoS 2
TL;DR: In this article, the half-metallicity of the CoS was investigated by means of density functional full-potential linearized augmented plane wave calculations within both the local spin-density approximation (LSDA) and the generalized gradient approximation (GGA).
Journal ArticleDOI
Ruderman-Kittel-Kasuya-Yosida-like ferromagnetism in MnxGe1-x.
TL;DR: The nature and origin of ferromagnetism in magnetic semiconductors is investigated by means of highly precise electronic and magnetic property calculations on MnxGe1-x as a function of the location of Mn sites in a large supercell, finding that the coupling is not always ferromagnetic (FM), even for large Mn-Mn distances.
Journal ArticleDOI
Structural, electronic, and optical properties of NiAl3: First-principles calculations
TL;DR: In this article, a density-functional analysis of the structural, electronic, and optical properties of the NiAl was performed using the full-potential linearized augmented plane wave method within the generalized gradient approximation to the exchange-correlation potential.
Journal ArticleDOI
Peculiar Rashba Splitting Originating from the Two-Dimensional Symmetry of the Surface
Kazuyuki Sakamoto,Haruya Kakuta,Katsuaki Sugawara,Koji Miyamoto,Akio Kimura,Takuya Kuzumaki,Nobuo Ueno,E. Annese,Jun Fujii,Ayaka Kodama,Tatsuya Shishidou,Hirofumi Namatame,Masaki Taniguchi,Takafumi Sato,Takashi Takahashi,Tamio Oguchi +15 more
TL;DR: It is found that the peculiar Rashba effect is simply understood by the two-dimensional symmetry of the surface, and that this effect leads to an unconventional nonvortical Rashba spin structure at a point with time-reversal invariance.

Extremely Large Magnetoresistance in the Nonmagnetic Metal PdCoO_{2}
Hiroshi Takatsu,Hiroshi Takatsu,Jun J. Ishikawa,Jun J. Ishikawa,Shingo Yonezawa,Harukazu Yoshino,Tatsuya Shishidou,Tamio Oguchi,Keizo Murata,Yoshiteru Maeno +9 more
TL;DR: Extremely large magnetoresistance is realized in the nonmagnetic layered metal PdCoO(2), and the temperature dependence of the resistance becomes nonmetallic for this field direction, while it remains metallic for fields along the [110] direction.
