We report on a new type of correlated nanometer-scale pinning structure observed in a melt-processed (Nd0.33Eu0.38Gd0.28)Ba(2)Cu(3)O(y) (NEG-123). It consists of NEG/Ba-rich clusters in the stoichiometric NEG-123 matrix forming a lamellar array with a period of a few nanometers. These lamellas appear within regular twins, thus representing their fine(More)
The effect of high pressure and high temperature on electrical resistivity behavior of (Nd, Eu, Gd) Ba-Cu-O superconductor with 10wt %Ag<inf>2</inf>O addition was studied. This high T<inf>c</inf> superconductor was synthesized using the oxygen controlled melt growth process(OCMG). At room temperature, there was an initial drop in the resistivity of the(More)
Fluorescence correlation spectroscopy (FCS) is a sensitive technique used to probe size, concentration, flow velocity, and reaction kinetics in a dilute solution. Conventional FCS spectrometers achieve this sensitivity at the cost of using bulky optics. We demonstrate a technique that utilizes a single-mode optical fiber of 3.3 microm mode field diameter to(More)
