On the Magnetic Excitation Spectra of High Tc Cu Oxides up to the Energies far above the Resonance Energy
Satoshi Iikubo, Masafumi Ito, Akito Kobayashi +2
Magnetic excitation spectra c"(q,w) of YBa2Cu3Oy and La214 systems have been studied. For La1.88Sr0.12CuO4, c"(q,w) have been measured up to ~30 meV and existing data have been ana…
Studies on Magnetic Excitation Spectra of High-Tc Superconductors
Masafumi Ito, Yukio Yasui, Satoshi Iikubo +6
Magnetic excitation spectra c"(q,w) of YBa2Cu3Oy, La2-xSrxCuO4, La2-y-xNdySrxCuO4 and Nd2-xCexCuO4 are compared with those of model calculations, where q and w are the wave vector…
Magnetic Structures and Spin States of NdBaCo2O5
Minoru Soda, Yukio Yasui, Masafumi Ito +3
Neutron diffraction studies have been carried out on a single crystal of oxygen-deficient perovskite NdBaCo2O5 in the temperature range of 7-370 K. There have been observed, with d…
Effects of "Stripes" on the Magnetic Excitation Spectra of La1.48Nd0.4Sr0.12CuO4
Masafumi Ito, Yukio Yasui, Satoshi Iikubo +4
The wave vector(q)- and energy(w)-dependent magnetic excitation spectra c"(q,w), have been studied in the temperature(T) range of 10 K<T<150 K on single crystals of La1.48Nd0.4Sr0.…
Neutron Scattering Studies of Pyrochlore Compound Nd2Mo2O7 in Magnetic Field
Yukio Yasui, Satoshi Iikubo, Hiroshi Harashina +4
Neutron diffraction studies have been carried out in the applied magnetic field H(//[011]) on a single crystal of pyrochlore ferromagnet Nd2Mo2O7, whose Hall resistivity(r_H) has b…
