Enhancement of the irreversibility field by carbon substitution in single crystal MgB
E. Ohmichi, T. Masui, S. Lee +2
We report the detailed study of the irreversibility field {\hirr} of single crystals of Mg(BC) (=0, 2, 3.5, 5 and 7%) in strong magnetic fields of up to 40 T.…
Carbon-substituted MgB2 single crystals
Sergey Lee, Takahiko Masui, Ayako Yamamoto +2
Carbon-substituted MgB2 single crystals, Mg(B_1-xC_x)_2 of 0.3-1.0 mm size were grown for x=0.02-0.15 by a high-pressure technique. The doping dependence of lattice constants studi…
Re-appearance of antiferromagnetic ordering with Zn and Ni substitution in La_{2-x}Sr_xCuO_4
T. Machi, I. Kato, R. Hareyama +5
The effects of nonmagnetic Zn and magnetic Ni substitution for Cu site on magnetism are studied by measurements of uniform magnetic susceptibility for lightly doped La_{2-x}Sr_xCu_…
Superconductivity in SrRuO Mediated by Coulomb Scattering
Shigeru Koikegami, Yoshiyuki Yoshida, Takashi Yanagisawa
We investigate the superconductivity in SrRuO on the basis of the three-dimensional three-band Hubbard model. We propose a model with Coulomb interactions among the electro…
Zn-Neighbor Cu NQR in Zn-Substituted YBa2Cu3O7-d and YBa2Cu4O8
Y. Itoh, T. Machi, C. Kasai +4
We studied local electronic states near Zn in optimally doped YBa(CuZn_x)O and underdoped YBa(CuZn_x)O via satellite signals of plane-si…
