PREPARATION, STRUCTURE AND ELECTRIC PROPERTY OF La1-xMxFeyCo1-yO3(M=Sr, Ba)
Abstract:
La1-xMxFeyCo1-yO3(M=Sr,Ba,x=0.1~0.9,y=0.1~0.9) have been prepared. The crystal of La0.7Sr0.3FeyCo1-yO3(y=0.1,0.3) is rbombohedral. The crystal of other compounds is cubic. The lattice parameters of La1-xMxFeyCo1-yO3 increase with increasing the yvalue. The lattice parameters of La1-xSrxFe0.7Co0.3O3 decrease with the increase of the x value, but that of La1-xBaxFe0.7Co0.3O3 increase with the increase of the x value. All the compounds are semiconductors. Their resistivities increase with increasing the y value when x=0.3; decrease with increasing the x value when y=0.7 and x=0.1~0.5; and increase with increasing the x value when y=0.7 and x=0.5~0.9.
