Kurzfassung:
We present our last results on anomalous Hall effect (AHE) in (Co 41 Fe 39 B 20 ) x (Al–O) 100-x nanocomposites focusing on the possible correlation between temperature dependence of AHE and resistivity. It is shown that the temperature dependence of conductivity G =1/ R xx , where R xx is resistivity, for compositions with x =49-56% at 10K 〈 T 〈 T k follows the relation, where the parameters A, , T k depend on x . For x =47% this relation changes to the exponential law “1/2” R xx ∝ exp (Т 0 /T) 1/2 . The correlation between AHE resistivity R H (T) and resistivity 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 %.
