Veselago V. G. , Vorob'eva N. V. , Doroshenko R. A.
A change in the magnetostriction of Y3Fe5012 has been observed after the application of light. A large photoinduced effect is observed on both the plot of the magnetostrictive strain λ against the field and the plot of the saturation magnetostriction against the orientation of the magnetization.
