The incidence angle effect of evaporated permalloy films must be studied for its practical use as magnetic memory elements. It is difficult to obtain uniform magnetic properties and favourable magnetic orientation in a number of elements by the method of the point source, for example, conical basket resistor source. In the permalloy film deposited from the line source upon the inner surface of cylinder, the easy magnetization axis is in the circumferential direction of cylinder. On this occasion, the line source must be set in the position which coincides with the center line of cylinder. The line source for this investigation was operated by utilizing the wetting of molten permalloy material on the tungsten rod.
