TbFe₂ exhibits huge magnetostriction over 1000ppm. However, it is very difficult to control microstructure of TbFe₂ for the peritectic reaction in solidification. It has been growing interest that the alloy solidification under the microgravity environment yields a unique morphology. The magnetostriction of the microgravity sample was larger than the terrestrial gravity sample.
