TL;DR: In this paper, the spin susceptibility and spin-lattice relaxation rate of 51 V nuclear moments of CaV 4 O 9 with tetragonal structure have been measured and the first example of quasi-two-dimensional spin systems with spin gap was provided.
Journal ArticleDOI
Ferroelectric Transition Induced by the Incommensurate Magnetic Ordering in LiCuVO4
TL;DR: In this article, a ferroelectric transition occurring simultaneously with a helical spin order has been found in both the polycrystalline and single-crystal samples of LiCuVO 4.
Journal ArticleDOI
Studies of Impurity-Doping Effects and NMR Measurement5s of La1111 and/or Nd 1111 Fe-Pnictide Superconductors
TL;DR: In this article, two mechanisms of the Tc-suppression by the doped impurities have been found: one is the electron localization, which appears when the sheet resistance exceeds h/4e2=6.45 kohm, and another is the disappearance or reduction of the hole-Fermi-surface around the gamma point in the reciprocal space.

Studies on Effects of Impurity Doping and NMR Measurements of La 1111 and/or Nd 1111 Fe-Pnictide Superconductors
TL;DR: In this paper, two mechanisms of T c suppression by the doped impurities have been found: one is the electron localization, which appears when the sheet r... instead of the pair breaking effect expected for the S ± superconducting symmetry proposed as the most probable symmetry.

Superconductivity of LaFe1-yCoyAsO1-xFx
TL;DR: In this article, the superconducting system LaFe 1- y Co y AsO 1- x F x (x = 0.11) and its measurements of their electrical resistivity ρ were carried out and it was shown that the potential scattering does not seem to primarily suppress superconductivity.
