Hexagonal strontium-ferrite (SrM) thin films were deposited by sputtering with the target composition ratio N (Fe/Sr) in the range of 8–14. The discrepancy of the composition ratio between the films and the target was found and the deposited films were in Fe-rich. In the x-ray diffraction diagram, the observed diffraction lines varied with the composition of the target and preferential c-axis orientation can be observed in the film prepared with the target, where the composition N is 10. The grain shape as well as size was found to be independent of N. The magnetic easy axis was normal to the plane. The maximum saturation magnetization and coercivity in the perpendicular direction were about 300 emu/cc and 3.5 kOe, respectively, when the film was prepared with the target with N of 8. © 1999 American Institute of Physics.
