Ferromagnetic substances undergo so-called magnetic distortions, i.e, they exhibit lengthening or shortening parallel to the direction of magnetisation. Such changes are termed positive or negative magnetostriction. As is the case in crystal anisotropy, magnetostriction is also ascribable to the spin-orbit mutual potential energy, as this is a function of direction of magnetisation and the inter atomic distances. Due to magnetostriction, which corresponds to a spontaneous distortion of the lattice, a ferro magnet can reduce its total anisotropic and elastic energy.
Holmarc's Model No: HO-ED-INT-06M, Magnetostriction with Michelson Interferometer uses two mirrors in a Michelson arrangement to obtain the interference pattern. Due to the magnetostrictive effect, one of the mirror is shifted by variation in the magnetic field applied to a sample, and the change in interference pattern is observed.
