摘要：

The surface of La1-xCaxMnO3 (LCMO) films with x = 0.1, 0.33, 0.5, and 0.66 has been studied; a highly ordered grain pattern induced by strain is observed in films with x = 0.5 and 0.66. The strain is identified to result from thermal expansion mismatch between substrate and film, and thermal expansion anomaly may exist at a high temperature induced by possible phase transition in LCMO with x = 0.5 and 0.66. Such phenomenon is arresting on film growth and understanding colossal magnetoresistance materials as well as providing a new way to make ordered structures far application.
