摘要：

Films of La100-xCaxMnO2, where x = 34, 40 and 50, with perovskite structure, have been prepared by pulsed laser deposition. The films are non-epitaxial, polycrystalline and have cubic crystal structure at room temperature. The temperature variation of resistivity shows no evidence of an electrical phase transformation. The highest CMR observed is near 1800% at 55 K in a maximum applied field of 70 kOe (5600 kA/m). The results of temperature variation of susceptibility, hysteresis, resistivity and CMR properties follow a self-consistent behaviour.
