The effect of coupled magnetomechanical loading on magnetostriction and compressive strain of Fe–Ga alloys has been investigated. A shift from negative to positive magnetostriction was observed with increase in compressive stress on a Fe85Ga15 single crystal. Non-linear behavior of the compressive strain in different magnetic fields was observed during the compressive loading and unloading process. These phenomena can clearly be explained by a model based on the magnetic-domain-switching process. The Young's modulus can also be obtained from the measured stress–strain curves.
Research highlights► The stress–strain behavior was studied for Fe85Ga15 single crystal. ► A shift from negative to positive magnetostriction with increasing stress was seen. ► A nonlinear behavior of the strain was seen during the loading and unloading process.► These phenomena were explained by a model based on the domain switching process.
