Session D40 - Poster Session I.
POSTER session, Monday afternoon, March 12
Exhibit Hall, Washington State Convention Center
Pure and Fe-doped (upto 25%) YBCO samples were prepared and studied. An annealing technique[1] was devised for control and determination of O-stoichiometry. Using this technique, multiple chain oxygen desorption processes in pure YBCO were discovered[2]. Superconducting critical temperature was determined using magnetization measurements, and lattice constants were computed from x-ray diffraction studies. Details will be presented.[1]R. K.
