Anisotropic dielectric constant of the parent antiferromagnet Bi2Sr2MCu2O8 (M=Dy, Y and Er) single crystals
T. Takayanagi, T. Kitajima, T. Takemura +1
The anisotropic dielectric constants of the parent antiferromagnet Bi2Sr2MCu2O8 (M=Dy, Y and Er) single crystals were measured from 80 to 300 K. The in-plane dielectric constant is…

Transport Properties in (Na,Ca)Co_2O_4 Ceramics
T. Itoh, T. Kawata, T. Kitajima +1
The resistivity and thermopower of polycrystalline (Na,Ca)Co_2O_4 were measured and analyzed. Both the quantities increase with x, suggesting that the carrier density is decreased…
