Insulator-metal transition and giant magnetoresistance in La 1-x Sr x MnO 3
TL;DR: Insulator-metal phenomena depending on band filling, temperature, and external magnetic field have been investigated for prototypical double-exchange ferromagnets, namely, crystals of crystals of La 1-x, showing large negative magnetoresistance around the ferromagnetic transition temperature.
Journal ArticleDOI
Giant Magnetotransport Phenomena in Filling-Controlled Kondo Lattice System: La1-xSrxMnO3
Yoshinori Tokura,Akira Urushibara,Yutaka Moritomo,Taka-hisa Arima,Atsushi Asamitsu,G. Kido,Nobuo Furukawa +6 more
TL;DR: In this paper, the authors show that the resistivity changes with the magnitude of temperature or field-induced magnetization in a single crystal of La 1-x Sr x MnO 3 near the critical composition (x ≈ 0.17).
Journal ArticleDOI
Optical transitions in quantum ring complexes
Takashi Kuroda,Takashi Kuroda,Takaaki Mano,Tetsuyuki Ochiai,Stefano Sanguinetti,Stefano Sanguinetti,Kazuaki Sakoda,Kazuaki Sakoda,G. Kido,Nobuyuki Koguchi +9 more
TL;DR: In this paper, a droplet-epitaxial technique was used to realize nanometer-sized quantum ring complexes, consisting of a well-defined inner ring and an outer ring.
Journal ArticleDOI
Anisotropy of superconductivity from MgB2 single crystals
M. Xu,H. Kitazawa,Yoshihiko Takano,Jinhua Ye,Kenji Nishida,Hideki Abe,Akiyuki Matsushita,Naohito Tsujii,G. Kido +8 more
TL;DR: In this paper, a superconducting transition with the onset temperature of 38.6 K was confirmed by both transport and magnetization measurements, and the upper critical field anisotropy ratio was estimated to be 2.6 from the magnetic field-temperature phase diagram for MgB2 single crystals.
Journal ArticleDOI
Comparison of the electron effective mass of the n-type ZnO in the wurtzite structure measured by cyclotron resonance and calculated from first principle theory
TL;DR: The electron effective mass of n-type ZnO obtained recently by the cyclotron resonance is compared with the quasiparticle mass predicted by the GW approximation which takes into account the dynamical screening effects within the random phase approximation.
