説明

<jats:p>The unidirectional solidification of the zone melt method was performed in order to clarify the growth mechanism on Y-system superconductors. A sharp faceted interface of YBa<jats:sub>2</jats:sub>Cu<jats:sub>3</jats:sub>O<jats:sub><jats:italic>y</jats:italic></jats:sub> (123) crystals was obtained in the sample grown at the low growth rate of 1 mm/h. The volume of the 211 phase changed drastically from liquid to 123 crystal. These results lead to the idea that the necessary solute for peritectic reaction is provided through a liquid. Based on this idea, we developed a simple solidification model that is in good agreement with the experimental results.</jats:p>
