The permeability of plated ferrite films

The soft-magnetic properties of ferrite films deposited by ferrite plating are discussed. The crucial parameter in this respect is the initial permeability, /spl mu//sub i/, which is 28/spl plusmn/3 for an as-deposited film and 60/spl plusmn/5 for an annealed film on glass substrates. The origin of these relatively high values of /spl mu//sub i/ is discussed.
