Description
Permalloy 80 is an alloy of nickel, iron and molybdenum. It is a soft magnetic alloy with exceptionally high magnetic permeability. The alloy has a low coercivity, near zero magnetostriction, and significant anisotropic magnetoresistance. The low magnetostriction is critical for industrial applications, where variable stresses in thin films would otherwise cause a ruinously large variation in magnetic properties.
