Abstract

The magnetic field response of Jahn-Teller distortion associated with the e orbital was investigated by x-ray diffraction in Fe_1-xMn _xCr₂O₄ for x 0 and 0.7. Successive structural domain rearrangements occurred when a magnetic field was applied along the [001]_c axis in the orthorhombic phase of FeCr₂O ₄. The domain rearrangements caused significant magnetostriction, which was observed by using a strain gauge. Reversible magnetostriction also appeared just above the structural transition temperature T_S1 in Fe_0.3Mn_0.7Cr₂O₄, in which T _S1 meets the ferrimagnetic transition temperature T_N1 by Fe substitution.
