Abstract
The amplitude dependence of shear modulus in CoPt alloy / 50.4% at. Pt / in disordered, ordered and partially ordered state was investigated. The distinct minimum of modulus for shear strain amplitude γ = 3.10-4 observed only in the case of disordered alloy is due to magnetomechanical hysteresis and can be successfully described basing on Smith and Birchak theory.
