Hall coefficient and Hc2 in underdoped LaFeAsO0.95F0.05
Y. Kohama, Y. Kamihara, S. Riggs +5
The electrical resistivity and Hall coefficient of LaFeAsO0.95F0.05 polycrystalline samples were measured in pulsed magnetic fields up to m0H = 60 T from room temperature to 1.5 K.…
Ferromagnetic spin fluctuation in LaFeAsO1-xFx
Yoshimitsu Kohama, Yoichi Kamihara, Masahiro Hirano +3
The F doped LaFeAsO, a recently discovered superconductor with the high Tc of 26 K, has been studied by the resistivity, magnetic susceptibility, and heat capacity measurements in…
Possible unconventional superconductivity in iron-based layered compound LaFePO: Study of heat capacity
Yoshimitsu Kohama, Yoichi Kamihara, Hitoshi Kawaji +3
Heat capacity measurements were performed on recently discovered iron based layered superconductors, non doped LaFePO and fluorine doped LaFePO. A relatively large electronic heat…
Unconventional magnetic transition and transport behavior in Na0.75CoO2
T. Motohashi, R. Ueda, E. Naujalis +5
Here we report an unconventional magnetic and transport phenomenon in a layered cobalt oxide, NaxCoO2. Only for x = 0.75, a magnetic transition of the second order was clearly dete…
Anomalies in heat capacity of YBa_2Cu_3O_{6+x} in normal state
V. N. Naumov, G. I. Frolova, V. V. Nogteva +2
The temperature dependence of heat capacity for the samples of 90 K phase of YBa_2Cu_3O_{6+x} with x = 0.85, 0.90 and 0.95 was investigated above T_c. For separating the heat capac…
