Ferrite Tape
(OP)
Does anyone know where I can buy ferrite tape? I assume this is magnetic ceramic ferrite particles in an adhesive binder?

Not much scientific info on their site, the media on their storage tapes is referred to as 'MP' and 'thin film.' MP is metal particulate, thin film is evaporated metal.

I believe that oxides (magnetite, CrO2, barium ferrite, etc.) are less commonly used nowadays due to improvements in creating ultrafine metal particles and thin metal films.
For magnetic tape technology (a bit dated), see
Magnetic Tape Storage and Handling: http://www.clir.org/pubs/reports/pub54/
For samples, maybe start with cassette or data storage tapes.

McMaster-Carr (http://www.mcmaster.com/) sells various types of EMI/RFI shielding foils & tapes (copper foil, copper mesh, lead, etc.), a silver-containing acrylic latex coating($$$), adhesives and conductive sheet, etc. Just enter EMI in the 'Find Product' box.

"Nickel Alloy Foil
Protect electronic equipment from RFI, EMI, and magnetic interference that can cause failure and false signals. This soft-temper MU foil is made from a nickel-iron Alloy (80% nickel) that's easy to cut and hand form. Conform to ASTM A753-85 Alloy type 4. Width tolerance is ±.005" for 4" width; ±.010" for 15" width. Adhesive-backed foil has a pressure-sensitive adhesive on one side."
I believe ferrites are for things you want to magnetize ('hard' magnetic) whereas for shielding you use something 'soft' magnetic. Hope that helps.

Did you end up finding a supplier of ferrite tape? If so, I would be interested in knowing who it was. I am also in need of such a shield.
