Abstract

La_0.7Sr_0.3MnO_3-δ (LSMO) films have a large temperature coefficient of resistance (TCR: defined as 1/R dR/dT) at near room temperature. Bi_0.34La_0.33Sr_0.33MnO_3-δ (BLSMO) film in which La in LSMO is substituted by Bi, was deposited at low temperature, 400°C, by a laser ablation method. The BLSMO film on the SiO₂/Si (100) substrate is polycrystalline without any preferred orientations. The low-temperature deposition and the Bi substitution eliminate the Curie temperature of the BLSMO film, and raise its TCR. The film has a large TCR, more than 2%/K, in the wide temperature range of 10-150°C.
