The soft-magnetic properties of ferrite films deposited by ferrite plating
are discussed. The crucial parameter in this respect is the initial permeab
ility, mu(i), which is 28 +/- 3 for an as-deposited film and 60 +/- 5 for a
n annealed him on glass substrates. The origin of these relatively high val
ues of mu(i) is discussed.
