I am interested in magnetic thin films, and was thinking about evaporated vs sputtered films.
My understanding is that typically sputtered films are more dense than their evaporated counterpart.
I was looking at a couple papers, which used Ni films one set evaporated and the other sputtered, both measuring the same effect. However the sputtered films showed the effect at a much lower applied field.
And I was curious as to whether this may have something to do with the densities of the films themselves. If the sputtered films was more dense than a magnetic path would be easier to form within the material compared with a less dense equivalent.
Is that a reasonable assumption to make? If not what am I missing in my thinking?
