what is the typical magnetoresistance we get? I mean the maximum resistance (in ohms) when the magnetization of the FM layers are antiparallel (i am not asking the GMR ratio delta r/ro).

Is it in the order of few tens of ohms, hundreds of ohms, kilo ohms ?

i just want rough estimate. all references i saw talk about the gmr ratio only, not the actual resistance.

thank you.
