We investigate factors affecting the movement of sputtered species and the (1010) texture formation of hexagonal-close-packed Co[sub 63]Cr[sub 31]Mn[sub 6] (CoCrMn) layers in magnetic recording media. Deposition conditions and underlayers rendering high mobility of the sputtered species promote the (1010) texture of the CoCrMn film. Elemental effects are studied by substituting manganese with a series of 3d transition elements (Ti, V, Cr, Fe, Ni, and Cu) in the CoCrMn films. The results suggest that the chemical characteristics of manganese, the preference of bonding with different elements (especially with cobalt), is important in the texture formation of CoCrMn films. © 2004 American Institute of Physics.
