Impact of lithium composition on the thermoelectric properties of the layered cobalt oxide system LixCoO2
T. Motohashi, Y. Sugimoto, Y. Masubuchi +5
Thermoelectric properties of the layered cobalt oxide system LixCoO2 were investigated in a wide range of Li composition, 0.98 >= x >= 0.35. Single-phase bulk samples of LixCoO2 we…
Room-temperature ferromagnetism in Sr_(1-x)Y_xCoO_(3-delta) (0.2 < x < 0.25)
W. Kobayashi, S. Ishiwata, I. Terasaki +4
We have measured magnetic susceptibility and resistivity of SrYCoO ( 0.1, 0.15, 0.2, 0.215, 0.225, 0.25, 0.3, and 0.4), and have found that SrYC…
Micro-structure and Magnetization of the 80-K Superconductor, TbSr2Cu2.7Mo0.3O7+d
V. P. S. Awana, Anurag Gupta, H. Kishan +5
The results of micro-structural and detailed magnetization studies are reported here for our recently published TbSr2Cu2.7Mo0.3O7+d superconductor with a transition temperature (Tc…
Oxygen and Cation Ordered Perovskite, Ba2Y2Mn4O11
M. Karppinen, H. Okamoto, H. Fjellvag +2
A three-step route has been developed for the synthesis of a new oxygen-ordered double perovskite, BaYMn2O5.5 or Ba2Y2Mn4O11. (i) The A-site cation ordered perovskite, BaYMn2O5+d,…
Structural and magnetic properties of MSr2Y1.5Ce0.5Cu2Oz (M-1222) compounds with M = Fe and Co
V. P. S. Awana, Anurag Gupta, H. Kishan +5
MSr2Y1.5Ce0.5Cu2Oz (M-1222) compounds, with M = Fe and Co, have been synthesized through a solid-state reaction route. Both compounds crystallize in a tetragonal structure (space g…
Enhanced thermoelectric properties of NaxCoO2 whisker crystals
G. Peleckis, T. Motohashi, M. Karppinen +1
Single-crystalline whiskers of thermoelectric cobalt oxide, NaxCoO2, have been grown by an unconventional method from potassium-containing compositions, and their transport propert…
