a, b The setup to measure longitudinal and transverse magnetostriction. The magnetostriction was measured by the capacitance between two metallic plates. The length change of the clamped sample leads to the change of the distance between the plates, and therefore the capacitance. c, d Longitudinal magnetostriction (top) and magnetization (bottom) as a function of the magnetic field for three crystalline orientations. The in-plane magnetostriction (B // x, y) is large, but for out of plane orientation (B // z), it is negligible. Magnetization displays the same slope for the three orientations. Dashed vertical lines indicate the threshold fields for domain inversion.
