Abstract

We report strong negative magnetoresistance in epitaxial PrBa2Cu3Ox films prepared by laser ablation on SrTiO3 substrates. Magnetoresistance appears at temperatures below ∼50 K. At 10 K its value reaches 90% in a magnetic field of 0.5 T. The magnetoresistance is strongly suppressed near 20 K where the Pr ions undergo antiferromagnetic ordering. Post annealing in flowing oxygen reduces the magnetoresistance by a factor of about three and slightly increases the antiferromagnetic ordering temperature.
