Magnetoelastic second-order strain effects in paramagnetic rare earth systems

Abstract

The qualitative and quantitative importance of second-order strain interactions in paramagnetic rare earth systems is demonstrated within a recently developed theory. In an applied magnetic field second-order strain interactions contribute measurable anisotropy effects to transverse sound velocities, which are as large as rotational effects and which are not described by the conventional linear-strain theory. For the example of SmSb, the magnetic-field-dependent and field-independent second-order strain effects turn out to be of the same order of magnitude as the corresponding first-order strain effects.
