We present our last results on anomalous Hall effect (AHE) in (Co41Fe39B20)x(Al–O)100-x nanocomposites focusing on the possible correlation between temperature dependence of AHE and resistance. It is shown that the temperature dependence of conductance G=1/Rxx, where Rxx is resistance, for compositions with x=49-56% at the temperature interval 10K<T<Tk follows the relation G=A(1+αlnT), where the parameters A, α , Tk depend on x. For x=47% this relation changes to the exponential law “1/2” Rxx ∝ exp (Т0/T)1/2. The correlation between AHE resistance RH (T) and resistance Rxx (T) can be described as RH ∝ (Rxx)m, where m increases from 0.38 to 0.58 with an increase of x from 49 to 56%.
