Abstract

Homocomposites consisting of two single-phase Sr2 FeMo O6 components with different grain sizes were prepared by a sol-gel method. Large low-field magnetoresistance (LFMR) effect was achieved for the composites. Experimental results show that the LFMR strongly depends on both the relative amounts of the two components and their grain sizes. The magnetoresistance value is found to be proportional to the square of the relative magnetization (M Ms). We suggest that the LFMR enhancement in the homocomposites compared with parent Sr2 FeMo O6 has its origin in the enhanced intergranular effects.
