RF Susceptor Heating (KHz range) Graphite Foil vs Iron Foil (or thin film)

[Watson]

Which do you believe is the best choice for a low temperature RF heating susceptor, i.e. - greatest rise in temperature vs. field strength. I am aware that Graphite (expanded graphite foil) has excellent thermal conductance in plane and therefore makes for very even heating patterns over large areas, however I am dealing with areas no larger than 10 sq/in.

I have not found much information comparing the susceptance properties of the two in similar geometries, frequencies and field strengths. Foils generally <2mm thickness. The system wattage does not exceed 100W.
