We consider the proximity effect between Dirac states at the surface of atopological insulator and a ferromagnet with easy plane anisotropy, which isdescribed by the \emph{XY}-model and undergoes aBerezinskii-Kosterlitz-Thouless (BKT) phase transition. The surface states ofthe topological insulator interacting with classical magnetic fluctuations ofthe ferromagnet can be mapped onto the problem of Dirac fermions in a randommagnetic field. However, this analogy is only partial in the presence ofelectron-hole asymmetry or warping of the Dirac dispersion, which results inscreening of magnetic fluctuations. Scattering at magnetic fluctuationsinfluences the behavior of the surface resistivity as a function oftemperature. Near the BKT phase transition temperature we find that theresistivity of surface states scales linearly with temperature and has a clearmaximum which becomes more pronounced as the Fermi energy decreases.Additionally at low temperatures we find linear resistivity, usually associatedwith non-Fermi liquid behavior, however here it appears entirely within theFermi liquid picture.
