Abstract

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/R_xx, where R_xx is resistance, for compositions with x=49-56% at the temperature interval 10K<T<T_k follows the relation G=A(1+αlnT), where the parameters A, α , T_k 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 R_H (T) and resistance R_xx (T) can be described as R_H ∝ (R_xx)m, where m increases from 0.38 to 0.58 with an increase of x from 49 to 56%.
