Effect of Ti doping on the electrical transport and magnetic properties of layered compound Na0.8CoO2
W. Y. Zhang, Y. G. Zhao, Z. P. Guo +9
Effect of Ti doping on the electrical transport and magnetic properties of layered Na0.8Co1-xTixO2 compounds has been investigated. The lattice parameters a and c increase with x.…
Structural Phase Transitions and Sodium Ordering in Na0.5CoO2: a Combined Electron Diffraction and Raman Spectroscopy Study
H. X. Yang, C. J. Nie, Y. G. Shi +6
The nonstoichiometric NaxCoO2 system exhibits extraordinary physical properties that correlate with temperature and Na concentration in its layered lattice without evident long-ran…
Phase separation, effects of magnetic field and high pressure on charge ordering in y-Na0.5CoO2
H. X. Yang, Y. G. Shi, C. J. Nie +7
Transmission electron microscopy observations reveal the presence of complex superstructures and remarkable phase separation in association with Na-ordering phenomenon in y-Na0.5Co…
Off-axis electron holography and microstructure of Ba0.5Sr0.5TiO3 thin film grown on LaAlO3
H. F. Tian, H. C. Yu, X. H. Zhu +4
Epitaxial Ba0.5Sr0.5TiO3 thin films grown on the (001) LaAlO3 substrates with the ferroelectric transition of about 250K have been investigated by TEM and off-axis electron hologra…
Superstructure, sodium ordering and antiferromagnetism in NaxCoO2 (0.75<x<1.0)
Y. G. Shi, H. C. Yu, C. J. Nie +1
Transmission-electron-microscopy investigation reveals the presence of a superstructure with a doubled period of 2d110 in the NaxCoO2 materials for x ranging from 0.75 to 1.0. Syst…
Effects of Mn-substitution for Co on the structure and physical properties of NayCoO2
W. Y. Zhang, H. C. Yu, Y. G. Zhao +4
Structure, transport and magnetic properties have been investigated for layered NaCo1-xMnxO2 materials. With the increase of Mn-doping amount, measurements of x-ray diffraction ind…
