: The nanocrystalline Fe82Nb7B10Cu1 soft magnetic ribbons were treated with the mixture gas flow of ammonia and hydrogen at 673 K. The influence of the nitridation treatment was studied by the low-frequency permeability spectra. The result shows that this kind of nitridation treatment can improve the soft magnetic properties under some application conditions. The reason for the improvement of the soft magnetic......
