Addition of nanoparticle dispersions to enhance flux pinning of the YBa2Cu3O(sub 7-x) superconductor
Article Abstract:
A method for achieving the dispersion of 8-nm-sized nanoparticles in YBa2Cu3O(sub 7-x) (YBCO) with a high number of density, which increases the critical current by a factor of two or three for high magnetic fields is described, which will help in enhancing the flux pinning of YBCO superconductor. The results of the studies indicate that the YBCO maintains a coherent structure as it grows around the 211 material.

Magnetic impurity formation in quantum point contacts
Article Abstract:
Extensive numerical density-functional calculations that reveal the formation of an electronic state with a spin-1/2 magnetic moment in the channel under very general conditions are presented. It is shown that such an impurity will also form at large magnetic fields, for a specific value of the field and sometimes even at the opening of the transverse mode in the QPC.

Nature of the superconductor-insulator transition in disordered superconductors
Article Abstract:
The numerical simulations of the superconductor-insulator transition in two-dimensional disordered superconductors are reported. The huge magneto-resistance peak observed in disordered thin films might be relevant to the observation of the pseudo-gap phenomenon in underdoped high superconductors.
