Jh. Paterson et al., Complex permeability of soft magnetic ferrite polyester resin composites at frequencies above 1 MHz, J MAGN MAGN, 197, 1999, pp. 394-396
Composite soft magnetic materials consist of magnetic particles in a non-ma
gnetic matrix. The properties of such materials can be modelled using effec
tive medium theory. Measurements have been made of the complex permeability
of composites produced using ferrite powder and polyester resin. The succe
ss of various effective medium expressions in predicting the variation of c
omplex permeability with composition has been assessed. (C) 1999 Elsevier S
