a Temperature dependence of TCR for the 30 nm (La1-xPrx)0.67Ca0.33MnO3(LPCMO)/ NdGaO3(NGO) films at various doping levels (x = 0–0.35) at zero field. The inset shows the corresponding ρ-T curves. b TC and TCR (peak value) as a function of the Pr doping level x, extracted from the ρ-T curves measured during cooling.
