Temperature responses of magnetic permeability have been studied for several domestic grades of radiofrequency ferrites having prospect for extreme electronics devices operating at 200—250 ^oC. At least two of these ferrite grades may develop a permeability figure of above 2000 at these temperatures. Shielding the magnetic dispersion stream of ring samples gives potential for an additional 15—30 % increase in magnetic permeability.

Extreme electronics devices, high temperature ferrite, magnetic dispersion stream shielding.
