Laser deposition of barium ferrite films with a varying substrate temperature was studied. It was observed that the film exhibits both c-axis orientation normal to the film plane and in-plane c-axis orientation and the grains in the film show both circular and elongated shapes. The perpendicular and in-plane coercivities were found to be 4149 and 4291 Oe and the film has almost isotropic properties. The magnetic properties, grain shape and crystalline orientation of the film with a varying substrate temperature during film growth were close to those of the film deposited with a post annealing and different to those of the film deposited with in-situ heating.
