Research Abstract

Detailed structural information on fluxon is important to make clear the mechanism of superconductivity and promote the electromagnetic studies. As the small-angle neutron scattering technique provides a useful information in the magnetic flux structure in type II superconductors, we applied this technique for following intensive studies together with scanning Hall probe technipue, magnetization and electrical resistivity measurement. (1) Anisotropy, dimensionality of FLL and magnetic phase diagram. (2) Structural deviation of FLL by pinning. (3) Dynamics of FLL due to phase transition and dimensional cross-over. (4) Inhomogeneous structure of FLL in LSCO single crystal. (5) Detailed structure of FLL by means of STM/STS.(6) Local magnetic flux distribution by means of scanning Hall probe measurement. (7) Analysis of magnetization process based on electromagnetic theory. The final discussion meeting was held at Kyoto on 2nd of March.
