Uffylike -Fe2 O3 grows on the surface with the nanowires by way of the post-annealing in air. The coercivity with the assynthesized nanowires is above 684 Oe within the temperature array of 5 to 300 K, that is drastically greater than that of the bulk Fe. Via the annealing course of action in air, the coercivity plus the exchange field are evidently improved. Each the coercivity plus the exchange field enhance with growing TA and attain their maximum values of 1,042 and 78 Oe, respectively, at TA = 4 h. The magnetic measurements show that the efficient anisotropy is improved with increasing the thickness with the -Fe2 O3 by annealing. The huge values of coercivity and exchange field, as well as the high surface region to volume ratio, may perhaps make the fluffy Fe@-Fe2 O3 core-shell nanowire a promising candidate for the applications on the magnetic drug delivery, electrochemical power storage, gas sensors, photocatalysis, and so forth.Cao et al.
