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.

使用反铁磁过渡金属氧化物，钴氧化物CoO，我们研究了磁场下的马氏体相的晶畴（变体）的重排行为。结果发现，重排发生在某些特定的条件下，与材料的磁性无关，并通过引入磁剪切应力值，成功地将重排条件定量化和推广化。
