We have measured the resistivity, special heat and AC magnetic suceptibility versus temperature in La1-xCaxMnO3(LCMO) bulk samples with x=0.3, 0.4, 0.5, 0.6. In the LCMO (x=0.3 and 0.4) samples a transition from dρ/dT0 was observed, accompanied by a peak in specific heat. In AC magnetic suceptibility measurement, a ferromagnetic and an antiferromagnetic transitions were observed in LCMO (x=0.5) sample.
