Abstract:

La_2/3Sr_1/3MnO₃: Ag_x (LSMO: Ag_x) polycrystalline composites were prepared by co-precipitation method. Structure and performance of La_2/3Sr_1/3MnO₃: Ag_x were investigated by X ray diffraction and R-T measurement. Results show that, all samples are perovskite structure. With the addition of Ag increased, the volume and conductivity of LSMnO: Ag_x were increased accordingly. The resistivity of the samples (x=0.30, 0.40) is only 10% of the pristine. The TCR of LSMO: Agx (x=0.3) is obtained maximum value of 3.39% as the Z value 0.50. It’s perhaps the proper candidate material to be high temperature electrode or near room temperature bolometer and infrared devices.
