Electroplating of high damping material for trailing shield in a perpendicular magnetic recording writer

A method of forming a trailing shield used in a write head, the method comprising:

• adding Fe2+, Co2+, Ni2+ and a transition metal salt to an aqueous solution;
• and
• applying a pulse to the aqueous solution according to a pulse waveform to form the trailing shield, wherein a composition of the trailing shield comprises FewCoxNiyMz,
• wherein:
• Fe is iron, Co is cobalt, Ni is nickel and M is metal;
• w, x, y and z are the concentrations of Fe, Co, Ni and M, respectively, in the composition and are in atomic percent (%);
• M is comprised of a 3d, 4d, and 5d transition metal;
• w is between 15 to 70, x is equal to or less than 10, y is between 20 to 70 and z is between 2 to 10, and w+x+y+z=100.
