Abstract :
A high sensitivity flux-gate magnetometer sensor element has been developed by electrodepositing permalloy films on cylindrical conductor substrates with magnetic easy-axis in the axial direction. The cylindrical films are of 2½" length, ¼" diameter and vary in thickness from 2 to 12 tousand angstroms. Film composition is 81% Ni and 19% Fe adjusted to zero magnetostriction. The resulting films exhibit an anisotropy field, Hk, of 1 Oersted and less than 5 degrees for the dispersion angie α90.
