    • Some magneto-dynamic properties of type II superconductors 

      Chou, Chan Shin (University of St Andrews, 1978) - Thesis
      The possibility of making a refrigerator by mechanically induced flux flow to transfer heat in a type II superconductor has been examined. Heat generation due to flux flow was sufficient to destroy the cooling effect over ...

    • Destruction of superconductivity by a current 

      Mukherjee, Benoy Kumar (University of St Andrews, 1971) - Thesis
      We have carried out an experimental investigation of the resistance transition in Indium and Thallium wires when superconductivity is destroyed by a current. Our results, as well as those obtained previously by other ...

    • Some properties of the dynamic intermediate state in type 1 superconductors 

      Lerski, Richard A. (University of St Andrews, 1974) - Thesis
      The high resolution magneto-optic method using the Faraday effect in thin films of EuS:EuF₂has been used to observe the dynamic intermediate state induced by the passage of an electric current or a heat current through ...

    • AC losses in superconducting niobium 

      Al-Huseini, Fahad A. (University of St Andrews, 1973) - Thesis
      This thesis is concerned with measurements of alternating field losses in cylindrical rods of niobium in its superconducting state. Six samples have been investigated each with a different surface condition, Magnetization ...

    • Vibrational and electronic properties of impurities in semiconductors 

      Noras, James M. (University of St Andrews, 1978) - Thesis
      Properties of impurities in semiconductors have been investigated by means of absorption spectroscopy. The studies have concentrated not on one topic but on a range of types of impurity behaviour: they may be summarized ...
