The single-domain particles, especially FeCo fine particles have many applications in magnetic information technology. We have prepared Fe1−xCox fine particles for different x by borohydride method and measured the magnetic and structural properties of the samples. We have then determined the variations of coercivity and anisotropy energy versus x in Fe1−xCox fine particles. The obtained results have been analyzed on the basis of various magnetic anisotropies. Magnetic anisotropies affect the coercivity of the medium for each x as follows: shape and crystal anisotropies for x=0x=0, surface and crystal anisotropies for x=1x=1, shape, induced and crystal anisotropies for x=0.3x=0.3 and 0.5, and shape and induced anisotropies for x=0.45x=0.45.
