Effect of Reducing Atmosphere on the Magnetism of Zn1-xCoxO Nanoparticles
M. Naeem, S. K. Hasanain, M. Kobayashi +4
We report the crystal structure and magnetic properties of Zn1-xCoxO nanoparticles synthesized by heating metal acetates in organic solvent. The nanoparticles were crystallized in…
Characterization of Magnetic Components in the Diluted Magnetic Semiconductor ZnCoO by X-ray Magnetic Circular Dichroism
M. Kobayashi, Y. Ishida, J. l. Hwang +12
We report on the results of x-ray absorption (XAS), x-ray magnetic circular dichroism (XMCD), and photoemission experiments on {\it n}-type ZnCoO () thin film,…
High-energy spectroscopic study of the III-V nitride-based diluted magnetic semiconductor GaMnN
J. I. Hwang, Y. Ishida, M. Kobayashi +12
We have studied the electronic structure of the diluted magnetic semiconductor GaMnN ( = 0.0, 0.02 and 0.042) grown on Sn-doped -type GaN using photoemission an…
Transport properties of the heavy fermion superconductor PrOsSb
H. Sugawara, M. Kobayashi, S. Osaki +4
We have measured the electrical resistivity, thermoelectric power, Hall coefficient, and magnetoresistance (MR) on single crystals of PrOsSb, LaOsSb and N…
Novel features in the flux-flow resistivity of the heavy fermion superconductor PrOsSb
M. Kobayashi, H. Sato, H. Sugawara +2
We have investigated the electrical resistivity of the heavy fermion superconductor PrOsSb in the mixed state. We found unusual double minima in the flux-flow resistiv…
