本文的主要目的是研究在拮抗材料YBCO和LCMO之间界面上YBCO的B 1G模式声子的因素。拉曼光散射是用于执行这项工作的技术。所研究的超晶格是YBA 2 Cu 3 O 7/la 2/3 Ca 1/3 Mno 3的薄膜,厚度不同。This study appears the shrinking of the SC-gap throw the 340 cm -1 due to the effect of the LCMO electrons which go through the YBCO and causes breaking of copper pairs, therefore it seems that the YBCO goes from the optimal doped case to the under doped case and that suppress the SC gap Keywords: Superconducting (SC) gap, 340 cm -1 phonon, Superlattices.版权所有©C2024Benghazi的University。this.open.access.Article.IS分布在CC BY-NC-ND 4.0许可下
