The perovskite (La/sub 1-x/Ca/sub x/)CoO/sub 3/ (O less than or equal to x less than or equal to 0.6) was prepared under high oxygen pressures. The rhombohedral distortion decreases with increasing x and the phase becomes cubic at x = 0.5. From the results of magnetic measurement, it was found that the cobaltite with x greater than or equal to 0.05 is ferromagnetic. This result is explained by the itinerant-electron model.
