The data seems kind of counterintuitive to me. Increasing magnetic permeabibility with temp seems analagous to increasing electrical conductance, which I thought decreased at higher temps. Perhaps my perception and/or my logic are/is flawed.
In any case, thanks for the info.
I have a Hall sensor application that uses a Sm2Co17 rare earth magnet and a 1010 CRS pole piece. I am interested in performance over a temperature range from 25C to 150C. I can find properties of the Sm2Co17 over temp, but I can find virtualy nothing on the steel. Can anyone help me find data...
