Magnetotransport properties in purple bronze Li $_{0.9}$ Mo $_{6}$ O $_{17}$ Single Crystal

H. Chen, J. J. Ying, Y. L. Xie +3

We have measured resistivity along the a, b and c axes of Li $_{0.9}$ Mo $_{6}$ O $_{17}$ single crystal. The anisotropy $ρ$ $_{c}$ / $ρ$ $_{a}$ and $ρ$ $_{c}$ / $ρ$ $_{b}$ is given, confirming the q…

Rearrangement of Sodium ordering and its effect on physical properties in $N a_{x} C o O_{2}$ system

T. Wu, K. Liu, H. Chen +4

We systematically study Raman spectroscopy of cleaved Na $_{x}$ CoO $_{2}$ single crystals with 0.37 $\leq$ x $\leq$ 0.80. The Raman shift of A $_{1 g}$ mode is found to be linearly depende…

Giant isotope effect and spin state transition induced by oxygen isotope exchange in ( $P r_{1 - x} S m_{x})_{0.7} C a_{0.3} C o O_{3}$

G. Y. Wang, X. H. Chen, T. Wu +3

We systematically investigate effect of oxygen isotope in $(P r_{1 - x} S m_{x})_{0.7} C a_{0.3} C o O_{3}$ which shows a crossover with x from ferromagnetic metal to the insulator with spin-sta…

Effect of iron-doping on spin-state transition and ferromagnetism in Pr $_{0.5}$ Ca $_{0.5}$ CoO $_{3 - δ}$ cobalt oxides

X. G. Luo, X. Li, G. Y. Wang +2

Resistivity and dc magnetization measurements were performed for the polycrystalline Pr $_{0.5}$ Ca $_{0.5}$ Co $_{1 - x}$ Fe $_{x}$ O $_{3 - δ}$ ( $x$ = 0, 0.05, 0.10 and 0.15) samples. The as-…
