Ferromagnetic resonance in Y(3)Fe(5)O(12) nanofibers

• Continuous bead-free polycrystalline yttrium iron garnet (YIG) nanofibers 100 mu m long and 50-100 nm in diameter were sintered by sol-gel calcination assisted electrospinning. Room temperature ferromagnetism in YIG fibers is indicated by a well formed M-H hysteresis loop with about 70% of remnant magnetization to the saturated value reached at 150 Oe. Broad band microwave spectroscopy revealed strong asymmetry of ferromagnetic resonance lines that conforms to a three orders of magnitude shape aspect ratio of YIG nanofibers.
