Stress annealing (SA)-induced magnetic anisotropy is known in iron, nickel, and cobalt-based ferromagnetic metallic glass ribbons and it has already been used in commercial processes. Uniaxial elastic strain is introduced by SA and is quenched into t

Traditionally the study of the magnetocaloric effect (MCE) in amorphous and nanocrystalline alloys has been focused on Fe and rare earth based compositions. However, they present problems that hinder their application such as the high price of rare e

Nanocrystallisation of Fe75Cu1Nb3Si8B13 under tensile stress results in a creep induced anisotropy which, at room temperature, is characterised by a magnetic easy axis along the stress axis. However, this magnetic easy ribbon axis becomes a magnetic
