Some modern models of neutron star evolution predict that initially large
magnetic fields rapidly decay down to some saturation value $\sim {\rm
few}\times 10^{13}$ G, lower magnetic fields do not decay significantly
\citep{Pons09}. It is difficult to check predictions of the model for initially
highly magnetized objects on the time scale of few million years. We propose to
use Be/X-ray binaries for this purpose. We apply several methods to estimate
magnetic fields of neutron stars in these accreting systems using the data
obtained by the RXTE satellite \citep{Galache05}. Only using the most modern
approach for long period NSs proposed by \citet{Shakura11} we are able to
obtain a field distribution compatible with predictions of the theoretical
model of field decay.
