FeCoB　films　with　gradient　B　doping　were　deposited　by　a　composition　gradient　sputtering　method　under　different　sputtering　pressure.　Good　soft　magnetic　performances　with　magnetic　anisotropy　field　of　142　Oe　and　ferromagnetic　resonance　frequency　of　4.82　GHz　were　obtained　at　zero　bias　field.　It　is　interesting　to　note　that　the　magnetic　anisotropy　of　the　films　rotates　by　90　degrees　by　changing　the　sputtering　pressure　from　0.2　to　0.5　Pa,　which　can　be　attributed　to　the　stress　transition　from　compressive　to　tensile.　This　provides　a　possible　method　to　in-situ　construct　complex　magnetic　anisotropy　by　controlling　the　sputtering　pressure.　(c)　2017　Published　by　Elsevier　B.V.
