The main objective of this work is to characterize the dependence on the applied magnetic field of both the Young’s modulus (∆E-effect) and the specific damping capacity (∆Ψ-effect) in pure nickel and iron specimens. The high quantity of direct and indirect information they provide requires very precise and accurate results, which can be achieved by means of a recently developed experimental set-up. The experimentally measured ∆E- and ∆Ψ-effects in pure nickel and iron are in good agreement with magnetic domain theory and they show better magnetoelastic behaviour of nickel in comparison to iron. Keywords: magnetoelasticity, elastic modulus, damping, iron, nickel.
