  • Pressure effects on electrical properties of a manganate with nominal composition La1.0Ca2.0Mn2O7, which has a layered perovskite structure as majority phase, have been investigated under hydrostatic pressures up to 1.05 GPa by using a self-clamped CuBe piston-cylinder cell. An abnormal pressure effect was observed. At a pressure of 0.55 GPa, a large pressure resistance effect of 40% was observed in a lower temperature range of 5~150 K. Besides, it is found that the metal-insulator transition temperature increases at low pressure but deceases with further loading pressure.
