Hi Dan.
Two ferrite manufacturers I use are Stewart and Fair-Rite. Both of
them have catalogs containing great detail graphs of performance of
their various materials.
Some of the 43 and 44 ferrite materials have very good low frequency
performance. I would suggest, because I have no further details, that
you contact their respective engineers as to what materials, form
factors, and other considerations would work best.

I have always been reluctant to place ferrite beads in the ground

I see them frequently in reference designs for USB and Analog Audio.
What kind material should this be and what characteristics would this
type
of ferrite have. I am assuming this ferrite would not have 600 Ohm
impedance @ 100MHz
Thanks in advance,
