We have studied the influence of P and of plating current density on static/dynamic magnetic and electrical properties of CoNiFe high moment alloy. We found that morphology, electrical and magnetic properties of films with P content up to 10 at. % are quite different from those of pure CoNiFe. CoNiFeP morphology consists of a structure made of isolated islands with sizes varying between 10 and 50 mu m. We indirectly obtained resistivity in this structure by using high-frequency magnetic measurements. Film composition is weakly dependent on plating current density for values larger than 10 mA cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> . Coercivities increase up to 6400 A m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> and magnetization saturation is reduced to 1.0 T in CoNiFeP films. The most remarkable effect of P addition to CoNiFe is the increase of resistivity over two order of magnitude with values of 5.2x10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-5</sup> Omegam compared to 2.4x10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-7</sup> Omegam of pure CoNiFe. We also found that the ferromagnetic resonance of CoNiFeP alloy is 3 GHz for sample with 10 at. % P and a performance factor (BF) of ~ 4x10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</sup> T s <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> , which is a better performance than bulk ferrite.
