What is it about?
This is Chapter 3, Volume 20, of the Handbook of Magnetic Materials, published by Elsevier, editor K.H.J. Buschow. It is a review of the work on Galfenol and other Fe-based alloys, up to 2011. A detailed description of the magnetoelastic interactions taking place in this technologically interesting alloy system is included. Experimental results of elasticity, magnetosctriction, and structure are presented. Theoretical calculations of magnetostriction and elastic constants are compared with experimental results after details of the DFT method used to account for the spin-orbit coupling term are given.

Why is it important?
It reviews the peak period in the development of Galfenol and its related alloys, from discovery to 2011.
Perspectives
- A complete review of many aspects, both experimental and theoretical, of Galfenol and related alloys. - A good source of properties (structure, temperature, and magnetic field dependent), experimental and theoretical methods, and perspectives on future directions in Fe-based alloy systems
