Electron paramagnetic resonance (EPR) and AC Susceptibility measurements were carried out as a function of temperature on La0,7Ca0,3MnO3 polycrystalline samples. The samples displayed a transition from paramagnetic-insulator to ferromagnetic-metal at Tc around 261K. Tc was determined from the inverse of the real part of a.c. susceptibility (1/X’) vs temperature, which follows a simple Curie-Weiss behavior. The inverse of the EPR intensity also follows a Curie-Weiss type behavior down toTEPR = 253 K.. The structure of the samples as determined by X-Ray diffraction (XRD) corresponds to a single perovskite phase with orthorhombic unit cell.
