【 摘 要 】

Well-crystallized CoFe2O4 nanowires are grown by electrodeposition into anodic alumina oxide (AAO) membrane. The XRD and EDS analysis confirmed the synthesis of pure CoFe2O4 with average grain size ranging from 30 to 22 nm. The SQUID investigations revealed that the nanowires electrodeposited at -1.2 V exhibit a large remanent magnetization and high permanent internal magnetic field along the wire axis. The microwave studies emphasized a gyromagnetic resonance around 42 GHz. In addition, numerical simulations performed by HFSS showed good agreement with experimental results. As a consequence, such electrodeposited nanocomposite is a promising candidate for high-frequency microwave devices.
