| Description | We have developed a method for computationally simulating the spontaneous deformation that ferromagnets undergo when exposed to a magnetic field, referred to as magnetostriction, and how this changes as a function of temperature. Using this method we were able to explain the anomalous temperature dependence of the magetostriction of Fe, which has been a small mystery for over 50 years. |
| Exploitation Route | Our work provides a basis for investigations of more industry-relevant magnetostrictive materials such as Galfenol and Terfenol-D. |
