Abstract:

Nanocrystalline γ′-(Fe1-xNix)4N  thin films with different Ni mass fractions  were synthesized on single crystal Si (100) substrate by facing target magnetron sputtering. The Fe/Ni atom ratio,  structure, morphology and magnetic properties were characterized by means of X\|ray diffraction (XRD), scanning electron microscopy (SEM) and vibrating sample magnetometer (VSM). The results indicated that the stabilities of the structure were improved and the soft magnetic properties were optimized by doping Ni in the sample.

Key words: γ′-(Fe1-xNix)4N thin film, nanocrystalline, structure, magnetic property
