Abstract:	The perovskite La0.5Sr0.5MnO3-δ/La0.7Sr 0.3CoO3-δ (LSMO/LSCO) bilayers and LSMO/LSCO/LSMO trilayers are fabricated by pulsed laser deposition and their magnetic and magnetoresistive properties are investigated. The "waist"-like magnetic hysteresis for both the bilayer and trilayer is explained in terms of the inter-layer exchange coupling model based on the large difference in coercivity between LSCO and LSMO layers. The shrink of hysteresis with temperature is attributed to the temperature dependence of the magnetic crystalline anisotropy and conduction band width W. We observe smoothed remnant resistance of the multilayers over a rather wide temperature range (>100 K), while the magnetoresistance (MR) is not seriously damaged. © Springer-Verlag 1999.
