AB  - We describe the synthesis of novel monocrystalline FeCo nanowires encapsulated 
      inside multiwalled carbon nanotubes (MWNTs). These FeCo nanowires exhibit 
      homogeneous Fe and Co concentrations and do not contain an external oxide layer 
      due to the presence of insulating nanotube layers. The method involves the 
      aerosol thermolysis of toluene-ferrocene-cobaltocene solutions in inert 
      atmospheres. The materials have been carefully characterized using 
      state-of-the-art high-resolution transmission electron microscopy (HRTEM), 
      electron-energy-loss spectroscopy (EELS), scanning electron microscopy (SEM), 
      energy-dispersive X-ray analysis (EDX), electron diffraction, HREELS-STM 
      elemental mapping, X-ray powder diffraction, and SQUID magnetometry. We noted 
      that the formation of FeCo alloys occurs at relatively low pyrolytic temperatures 
      (e.g., 650-750 degrees C). These single-crystal nanowires, which have not been 
      reported hitherto, always exhibit the FeCo (110) plane parallel to the carbon 
      nanotube axis. The FeCo nanomaterials have shown large coercive fields at room 
      temperature (e.g., 900 Oe). We envisage that these aligned ferromagnetic 
      nanowires could be used in the fabrication of high-density magnetic storage 
      devices and magnetic composites.
