This paper describes the application of an Fe-based nanocrystalline ribbon as a shielding material for coaxial cable in the 10 MHz to 1GHz frequency range. A 0.01 mm thick Fe-based amorphous ribbon was converted into an Fe-based nanocrystalline ribbon by annealing it at 570 °C for 10 min. The ribbon exhibited high impedance characteristics when it was annealed in a transverse magnetic field. The noise attenuation value of cable covered with Fe-based nanocrystalline alloy ribbon annealed in a transverse magnetic field was 12.9 dB. This value exhibited 13 % higher than that of cable covered with Fe-based nanocrystalline alloy ribbon annealed without a magnetic field.
