dc.description.abstract本論文中，我們利用超快激發檢測光譜去研究摻鈣0.3的鑭鈣錳氧薄膜的超快動力行為，由實驗所得到的實驗數據和三溫模型(TTM)做比較，我們可以驗證實驗數據每個參數所對應的的物理機制，進而更了解每個參數是由自旋、晶格、電子、軌道哪些之間的交互作用所造成的，這些研究可以讓我們更了解龐磁阻材料在微觀裡所對應的物理機制。zh_TW
dc.description.abstractUltrafast dynamics of La0.7Ca0.3MnO3 thin films have been studied by femtosecond pump-probe spectroscopy. The transient-reflectivity changes (ΔR/R) through the LCMO thin films at various temperatures were measured. Compare our data with three temperature model (TTM), and we will understand that each parameter from experiment data was caused by spin、lattice、charge or obtial. These research can let us understand the physics mechanism of CMR material.en_US
