Preparation and transport properties of non-hydrated Na $_{0.5}$ CoO $_{2}$ single crystals

X. Z. Chen, Z. A. Xu, G. H. Cao +3

Single crystals of Na $_{0.5}$ CoO $_{2}$ were obtained through a flux method followed by de-intercalation of sodium. The Na $_{0.5}$ CoO $_{2}$ samples were found to be vulnerable to water…

Thermal Conductivity as a Probe of Quasi-Particles in the Cuprates

N. P. Ong, K. Krishana, Y. Zhang +1

In underdoped YBa_2Cu_3O_x (x=6.63), the low-T thermal conductivity Kappa_xx varies steeply with field B at small B, and saturates to a nearly field-independent value at high field…

Effect of the pseudogap on the Hall conductivity in underdoped YBa_2Cu_3O_6+x

Z. A. Xu, Y. Zhang, N. P. Ong

In underdoped YBa_2Cu_3O_x (YBCO) with x = 6.63, the opening of the pseudogap at T^* ~ 160 K has a strong effect on the Hall angle tan(theta). While the Hall response is significan…
