Abstract ： Electrical transport and low-field magnetoresistance (MR) are2/3 Ca1/3 MnO2 and YSZ being yttria stabilized zirconia). Different transport and MR behaviour are observed for x < 2% and x > 2%. In particular, the composite with x ≤ 1% shows a wide temperature window with a large constant MR below the transition. Based on the microscopy analysis, a possible interpretation is presented for different observations for x < 2% and x > 2% with emphasis on the boundary effect arising from insulating YSZ layers.
