N2 - The relation between the soft magnetic properties and local anisotropy fluctuation measured by the dynamic differential susceptibility method in Fe-Ni-Nb alloy films was clarified and discussed in comparison with Fe-Si-Al alloy films. Fe-Ni-Nb alloy films with excellent soft magnetic properties, 5 MHz values of μ eff = 6500 for 1000 A thick films were obtained. For Fe-Si-Al alloy films, the magnitude of μeff = 6500 is proportional to 1/s2 (where S is a structure constant) and independent of the value of Hk, while for Fe-Ni-Nb alloy films, the value of S is about one-tenth of that in Fe-Si-Al alloy films, and the magnitude of μeff 6500 does not depend on S. Rather, this magnitude is dependent on the value of Hk, and is almost equal to 4 π Ms/Hk, obtained from a rotational magnetization model in a uniaxial single-domain particle.
