Potentialities of La0.7Sr0.3MnO3 thin films for magnetic and temperature sensors at room temperature
Résumé
In this paper, the potentialities of the manganese oxide compound La0.7Sr0.3MnO3 (LSMO) for the realization of sensitive room temperature thermometers and magnetic sensors are discussed. For these two applications, the sensor performances are described in terms of signal to noise ratio especially in the 1 Hz-100 kHz frequency range. It is shown that due to the very low 1/f noise level, LSMO based sensors can exhibit competitive performances at room temperature.
