1. 1. Studies of systems related to high-Tc superconductors by electron microscopy and X-ray powder diffraction

   Författare :Ingrid Bryntse; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : New cuprate systems related to high temperature superconductors have been investigated and are reviewed. The synthesized samples have been studied mainly by transmission electron microscopy, energy-dispersive spectrometry and X-ray powder diffraction, in order to determine composition and structure of the formed phases.

3. 2. Synthesis and properties of substituted Hg-based superconductors

   Författare :Dmitriy A. Pavlov; Ingrid Bryntse; Lauri Niinistö; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hg-based cuprate superconductors; synthesis and structure determination; LiF flux; oxyfluorides; irrevrsibility line; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : This thesis is focused on studies of substituted Hg-based superconducting copper oxides ((Hg1-xMx)Ba2Can-1CunO2n+2+δ). These compounds are promising objects of investigation, not only from a fundamental point of view but also because of their high values of superconducting transition temperature (Tc) and irreversibility field (Hirr).
