Influence of Pr-doping on structural, electronic transport, magnetic properties of perovskite molybdates Sr1−xPrxMoO3 (0≤x≤0.15)

The effect of Pr-doping on structural, electronic transport, magnetic properties in perovskite molybdates Sr1−xPrxMoO3 (0≤x≤0.15) has been investigated. The Pr-doping at Sr-site does not change the space group of the samples, but decreases the lattice parameter a. The magnitude of resistivity ρ increases initially (x≤0.08) and then decreases with further increasing Pr-doping level x and ρ(T) behaves as T2 and T dependence in the low-temperature range blow T* and high-temperature range of 150 K
