The uniform and narrow-sized MWNTs-magnetic alloy NWs with a well-crystallized bcc (1 1 0) texture of FeCo along the easy axis were formed by introduction of MWNTs acted as a sintering inhibitor during annealing. The coercive field at room temperature increased two times higher than that of MWNT-free magnetic NWs due to the well-developed texture and the small grain size, which is slightly larger than the single domain size within the 10-15 nm range for most magnetic metals. As a result, the highly enhanced ferromagnetic NW mats with a MWNT-incorporated nanowire structure have shown great promise for providing a wide range of potential applications, including magnetic recording and ultrahigh-density magnetic storage devices operating room temperature.
