Abstract: Abstract:Magnetic and property characteristics of sputtered Fe65Ti13Co8Ni7B6Nb1 film in as-deposited and annealed conditions are examined. The film is transformed into various nanoscale and amorphous structures during annealing. Fully amorphous structure is obtained at 773–823 K, whereas nanocrystalline γ-fcc FeNi, cubic Fe(Ni) and FeNi phases evolve sequentially at various temperatures. Amorphization and nanocrystallization yield alterations in electrical, hardness and magnetic properties with good soft magnetic properties obtained at 898 K. Magnetic force images reveal stripe magnetic domain structures at 923–973 K, indicating the presence of the strong stress-induced perpendicular magnetic anisotropy due to the combined effect of the positive magnetostriction and the compressive stress.
