Abstract

La_0.8Ca_0.2MnO₃ thin films are investigated for anomalously high metal-insulator transition temperature T_p and ferromagnetic transition temperature T_c. At room temperature well above T_c, the ferromagnetic signals from the microwave studies suggest the presence of multiple magnetic spin systems. The T_p and T_c values are higher than of T_p and T_c for La_0.67Ca_0.33MnO₃ according to the bulk phase diagram which suggest that the properties are well beyond those seen in bulk phase diagram achievable in manganite thin films.
