概要
- 論文の詳細を見る
An electric field sensitive moving hot spot appeared on a GdBa_2Cu_3O_<7-δ> bar with following dimension, 0.65mm×0.65 mm×40 mm, when a dc voltage of 7 V was applied at room temperature. The spot moved to the negative electrode, and the direction of movement could be reversed time after time by switching the positive and negative electrode. The average velocity of the hot spot was 1.9 mm/min. The spot size increased with increasing voltage. This phenomenon is believed to be related to the ionic conduction by oxygen.
