| Research Abstract |
Using an antiferromagnetic transition metal oxide, the cobalt oxide CoO, we investigated the rearrangement behavior of the crystallographic domain(variant) of the martensite phase under the magnetic fields. As a result, we found the rearrangement occurs in some specific condition irrespective of the magnetism of material and succeeded in quantifying and generalizing of the rearrangement condition by introducing a value of magnetic shear stress.
