Structurally different surface regions are identified at both sides of the ribbon-shaped ^{57}Fe_{90}Zr_{7}B_{3} NANOPERM alloy. Though paramagnetic in the as-quenched state, the air side shows significant contribution of crystalline bcc-Fe that decreases towards the interior of the ribbon. After annealing at 480 °C, magnetic dipole interactions develop that are associated with enhanced number of ferromagnetic nanograins. Significant increase in the number of nanograins was revealed at the wheel side, while the one at the air side is almost saturated. The observed maze-type magnetic domains exhibit well developed structure with equally wide strips.
