摘要	We report the effects of biaxial strain on the charge ordering temperature T-co of the mixed-valent manganite perovskite oxide Pr0.5Ca0.5MnO3. Thin films were grown on SrTiO3, which has a 1.3% larger in-plane lattice parameter. Other substrates were used for comparison. Transport measurements combined with data from electron microscopy show that T-co is considerably enhanced. At thicknesses of the order of 10 nm, where the films are fully strained, T-co is above 320 K, more than 70 K above the bulk value of 250 K, while around 50 nm, where relaxation has set in, the enhancement is around 40 K. The bulk value is only reached at a thickness of about 150 nm.; We report the effects of biaxial strain on the charge ordering temperature T-co of the mixed-valent manganite perovskite oxide Pr0.5Ca0.5MnO3.
