Electrical transport and low-field magnetoresistance in La2/3Ca1/3MnO3/YSZ composites
2002
Electrical transport and low-field magnetoresistance (MR) are reported for (1-x)LCMO/xYSZ composites (0 2%. In particular, the composite with x≤1% shows a wide temperature window with a large constant MR below the transition. Based on microscopy analysis, a possible interpretation is presented for different observations for x 2% with emphasis on the boundary effect arising from insulating YSZ layers.
