## Abstract Low frequency noise and dynamic tunneling resistance have been studied in Co(80 Å)/Al~2~O~3~(12 Å)/Py(100 Å) magnetic tunnel junctions (MTJs) with and without asymmetric Si doping of the insulating barrier (Si ≤ 1.8 Å). Variation of the dynamic resistance and tunneling resistance with S
