Investigation of deposition parameters and output functions, and production of low coercivity films
MetadataShow full item record
The correlation of deposition parameters with output functions when using a novel rotating cryostat (RC) system to produce magnetic materials has been investigated here. In order to do this, an orthogonal design technique was applied for magnetic material production using a resistively heated furnace. The results of orthogonal analysis indicate that the thickness uniformity across the film was not greatly improved, due to the large standard deviation, but an optimum deposition rate was obtained by appropriate choice of control parameters. Furthermore, the orthogonal design process was applied to systematically optimise the production of low coercivity in iron films. The results indicate that the process can be easily optimised.
