| Abstract: | The compounds and films of La067Sr033FexMn1-xO3(x=0, 005, 010, 015) were prepared by the sol-gel technique and pulsed laser deposition method, respectively. The effect of Fe doping on the transport and photo-induced properties of La067Sr033FexMn1-xO3 film was investigated. Experimental results indicate that the Fe doping lowers the insulator-metal transition temperature, but increases the resistance. The photo-induced relative change in resistance increases initially with increasing temperature, then followed by a decrease.The maximum value of the relative change in resistance increases with increasing x, it reaching 38％ when x =015 The intriguing mechanism of photo-induced effect on the resistance was discussed in connection with lattice effect. |
