I. Introduction
Nanomaterials are experiencing a rapid development in recent years due to their existing and/or potential applications in a wide variety of technological areas such as electronics, catalysis, ceramics, magnetic data storage, and structural components. In the case of La2/3 Ca1/3MnO3, in spite of its critical temperature is lower than room temperature; it has been used in several technological applications. For instance, T. Zhao et al. [1] reported an all-perovskite Ferroelectric field effect transistor (FeFET) with a ferroelectric Pb( )O3 (PZT) gate and a colossal magnetoresistance (CMR) La0.8Ca0.2 MnO3 (LCMO) channel on Si, and the effects of electric and magnetic fields on the LCMO ( K) electrical resistance. This all perovskite FeFET has been considered as commercial semiconductor device. M. J. Montenegro et al. [2] studied the catalytic performance of carbon-based perovskite gas diffusion electrodes and thin films of identical perovskite catalyst phases (La0.6Ca0.4CoO3(LCCO), La0.7Ca0.3MnO3(LCMO) and La0.7Ca0.3Mn0.9Ni0.7O3 (LCMNO)) for battery applications. Y. Xu et al. [3] proposed materials like polycrystalline La0.67Ca0.33 MnO3, La0.67Sr0.33 MnO3, and La0.67Ba0.33MnO3 for magnetic refrigeration that can be realized by using the heat release or absorption caused by the magnetic entropy change of a magnetic material due to a magnetic field change. Other important applications of this material are in spin valves and read heads [4], [5]
