Polycrystalline perovskite manganites Bi1-xCaxMnO3 (x ≥ 0.8) have been prepared by standard ceramic technique, and their magnetic and electronic property are examined down to 5 K. Ferromagnetic moment and reduced resistivity are observed for Bi1-xCaxMnO3 (x ≥ 0.875), and also large negative magnetoresistances appear below Tc.
