Popis:	We have fabricated, using Jet Vapor Deposition, films of Pb doped rare-earth perovskite Mn oxides which show colossal magnetoresistance (CMR) effect. We have achieved epitaxial CMR films at a high deposition rate of typically 0.3 nm/s, uniformly over a large area. Films grown on LaAlO3 with a wide range of thickness (0.2–1.1 μm) show epitaxial characteristics. Scanning electron microscope analysis indicates that the surface is smooth. The measured magnetization and magnetoresistance show comparable performance compared to similar CMR films made by other methods.
