Some magneto-dynamic properties of type II superconductors
(University of St Andrews, 1978) - ThesisThe 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
(University of St Andrews, 1971) - ThesisWe 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
(University of St Andrews, 1974) - ThesisThe 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
(University of St Andrews, 1973) - ThesisThis 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
(University of St Andrews, 1978) - ThesisProperties 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 ...
