Abstract
La0.8Ca0.2MnO3 thin films are investigated for anomalously high metal-insulator transition temperature Tp and ferromagnetic transition temperature Tc. At room temperature well above Tc, the ferromagnetic signals from the microwave studies suggest the presence of multiple magnetic spin systems. The Tp and Tc values are higher than of Tp and Tc for La0.67Ca0.33MnO3 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.
