  Motivated by a recent experimental report on in-plane anisotropic resistivity
in the double-striped antiferromagnetic phase of FeTe, we theoretically
calculate in-plane resistivity by applying a memory function approach to the
ordered phase. We find that the resistivity is larger along an
antiferromagnetically ordered direction than along a ferromagnetically ordered
one, consistent with experimental observation. The anisotropic results are
mainly contributed from Drude weight, whose behavior is attributed to Fermi
surface topology of the ordered phase.
