Recrystalljzation of Non-Vacuum Derived Ba2ycu3o7-δ Films
Published online by Cambridge University Press: 28 February 2011
Abstract
Partial melting followed by recrystallization at lower temperatures during high temperature treatment of superconducting Ba2YCu3O7-δ films is associated with texture development In these films, partial melting is induced by rapid thermal annealing at a temperature slightly above the peritectic melting temperature of Ba2YCu3O7-δ. Short firing duration prevents segregation of liquid and permits recrystallization of the correct phase at around 920°C.
