Figure 3

Phase evolution as a function of the film thickness.

Phase diagrams for the (a) NNO/STO and (b) NNO/LAO systems, respectively. PM, PI and AFI denote paramagnetic metal, paramagnetic insulator and antiferromagnetic insulator, respectively. Two-phase region denotes the region where the metallic and insulating phases coexist and the temperature dependency of transport behavior is dominated by the metallic phase (see Supplementary Information for details). (c) R-T hysteresis width as a function of the NNO film thickness. Hysteresis width refers to the difference between TMI upon heating and cooling. (d) Negative MR at TN as a function of the NNO film thickness.
