Experimental verification of first-order rotational effects in the magnetoelastic properties of an antiferromagnet

Abstract

The experimental magnetoelastic properties of antiferromagnetic MnF2 are found in certain specific instances to be completely inconsistent with the usual small-strain magnetoelastic theory. Rigorous application of finite-deformation magnetoelastic theory including the effect of the rotational component of the shear deformation leads to results which are in excellent agreement with experiment. © 1970 The American Physical Society.
