Such materials are considered to have a potential for high frequency core material applications because of possibilites of obtaining high effective permeability and low coercive force. The addition of Ni content of approximately 0.5？1.5 at.% was found to be effective in improving the soft magnetic properties. The temperature dependence of magnetization measured by a SQUID magnetometer are found to be in good agreement with the spin wave theory. The spectroscopic splitting g values obtained by ferromagnetic resonance(FMR) experiments increase with increasing Ni content. The values of the spin wave stiffness increases from 62.7 meV ？2 to 95.2 meV ？2 with increasing the concentration of Ni. From these experimental results, the range of the exchange interaction are deduced. ？ 1995 IEEE English Amorphous alloys Annealing Coercive force Composition effects Crystallization Ferromagnetic resonance Iron alloys Magnetic permeability Magnetic variables measurement Magnetization Magnetometers Thermal effects Soft magnetic properties Spectroscopic splitting values Spin wave stiffness Magnetic materials Magnetic Properties of the Amorphous Fe-Zr-B-Ni Alloys Annealed below the Crystallization Temperature Article 10.1109/20.489812 1 IEEE Transactions on Magnetics, v.31, no.6, pp.3907 - 3909 IEEE Transactions on Magnetics 31 6 3907 3909 scopus 2-s2.0-0029408670 Article Amorphous alloys Annealing Coercive force Composition effects Crystallization Ferromagnetic resonance Iron alloys Magnetic permeability Magnetic variables measurement Magnetization Magnetometers Thermal effects Soft magnetic properties Spectroscopic splitting values Spin wave stiffness Magnetic materials amorphous Fe-Zr-B-Ni alloy
