Comment on 'The controlled charge ordering and evidence of the metallic state in Pr0.65Ca0.35MnO3 films'

In a recent letter (Lee Y P, Prokhorov V G, Rhee J Y, Kim K W, Kaminsky G G and Flis V S 2000 J. Phys.: Condens. Matter 12 L133), Lee et al have studi ed the transport properties of Pr0.65Ca0.35MnO3 thin films. They claimed th at they are able to control the charge-ordered state by means of the lattic e strains. We propose herein another alternative, since another indexation of the orientation of the film can be found leading to almost no distortion of the cell, as compared to that of the bulk compound.
