Amorphous films 3.5 μm thick of Fe81B13.5Si3.5C2 were deposited using conventional radio-frequency sputtering on planar glass substrates and cladded single-mode optical fibers of 80-μm diameter with a core diameter of 4 μm. The substrates were arranged in two configurations. In the first configuration the substrates (group I) were placed in contact with the water-cooled substrate table; in the second configuration (group II) the substrates were suspended about 8 mm above the substrate table. Ferromagnetic resonance (FMR) and vibrating sample magnetometer (VSM) measurements were used to study the bulk properties of the film and the longitudinal magneto-optical Kerr effect was used to study the magnetic hysteresis at the film surfaces. The group (I) samples were found to be magnetically softer than their group (II) counterparts. The magnetostrictive response of the coated fibers was studied using a Mach–Zehnder interferometer. The dependence of this response on annealing is also discussed.
