Magnetoelastic effects in metallic glasses

This paper reviews data in the literature and reports some new results on magnetoelastic (ME) effects in transition metal/metalloid glasses. All of the ME phenomena are presented in a coherent formalism based on the type of spin interaction from which they arise. Included are isotropic ME effects on mean interatomic spacing (e.g., anomalous thermal expansion and volume magnetostriction) and on the elastic modulus, as well as anisotropic ME effects on mean atom spacing (e.g., magnetostriction) and on the elastic constants (e.g., ’’morphic’’ and ’’ΔE’’ effects).
