Abstract
We present a thermodynamic framework to quantify the magnetization and magnetostriction of Galfenol alloys in response to magnetic fields, mechanical stress, and/or stress-annealing. The framework utilizes only physical parameters and thus provides useful information for material characterization. Furthermore, we formulate the model in state-space form, thus facilitating the computational implementation for design and control of dynamic Galfenol devices.
