The magnetic field dependence of the power-law exponent (gamma) of the magnetic 1/f noise and magnetoresistance were attached. To eliminate the magnetic after effect, each data point was obtained after the MTJ was stabilized at a certain magnetic field for 1000 s. Also, no RTN was observed in all measurements. However, the abrupt change of the exponent still occurred at the AP state during the magnetic reversal. This behavior was observed in all eight MTJs.
I'm quite confused about the physical meaning of the observed phenomenon. May I have any suggestion? Thanks a lot.
Steven Hi
I send you several articles where your question is considered in detail.

Dear Prof. Eppelbaum,
Thank you very much for your help. Since the principles in power lines and magnetic tunnel junctions are quite different, do you have any comment on the power-law exponent (γ) of the magnetic 1/fγ noise in magnetic tunnel junction systems?
Thanks a lot again for your attention.
Best regards,
Steven
