was examined under compressive loads up to 48 MP a. Magnetostrictions > 1.8 × 10

were observed for stresses greater than 20 MPa. Magnetization and magnetostriction were calculated for the magnetization rotation model, which was extended to include cubic anisotropy and compressive loading along the [111] axis. The effect of a distribution of magnetic moment directions is discussed.
