The results of study of bias voltage Ub and substrate temperature Ts influence on the texture of FeCo films with the thickness of 180 nm deposited on Si/SiO2 substrates by DC magnetron sputtering are presented. It is shown that the change of Ub from -250 V to 80 V leads to the growth of films with (110) texture. Further change of Ub from 80 V to 250 V causes the growth of films having (200) texture. Films deposited at Ub=0 and Ts=60-300oC have (200) texture. Further increase of Ts results in the change of film texture to (110). Keywords: FeCo films, magnetron sputtering, texture, coercitivity.
