Magnetic properties of CoCrTa/Cr thin films deposited with DC bias voltage ranging from 0 to -500V were studied. Three different kinds of biasing schemes were used ; Cr layer bias, Co layer bias, Cr and Co layers bias. In all cases, coercivity increased to a maximum value at -300V bias and decreased with further increasing bias voltage. When Cr layers were biased the cause of coercivity increase could not be interpreted by accounting the intensity change of Co (1011), (1010) and (1120) planes only and it is concluded contribution of Cr morphology change on CoCrTa grain separation must be substantial. The increase of coercivity in the CoCrTa biased specimens is understood as enhanced segregation of Cr with the increasing bias voltage. These and other contributions on the coercivity increment will be discussed in detail.
