Nickel–iron, cobalt–iron and aluminium–iron alloys

This chapter focuses on the magnetic properties of nickel-iron, cobalt-iron and aluminium-iron alloys, which are established soft magnetic materials. The authors consider how each alloy presents varying magnetic properties allowing them to be used for different scenarios. Properties such as magnetic permeability, saturation magnetisation, magnetostriction constant and magnetocrystal anisotropy constant are discussed and compared across the different alloy compositions.
