所谓的p带模式，即。e.在偏光显微镜下观察到的NiO的单个T畴内的精细层状图案，已被证实，与使用X射线技术，来自磁畴结构由于S-壁的存在，其晶体学方面的预测，正如在前面的文件。从所观察到的S畴在外加磁场中的行为来看，易磁化面（111）内的易磁化方向被确定为turnright.eps [11\bar2]，而不是turnright.eps [1\bar10]。通过Berg-Barrett方法观察磁畴结构，得到自发磁致伸缩的大小为：|e x x- e y y| =（9±3）×10 - 5和ez ' x ' /（ex ' x ' -ey ' y '）=-0.18 <$0.06，其中x '轴沿着自旋轴，z '轴沿着[111]。
The so-called p-band patterns, i. e. , fine lamellar patterns observable within a single T-domain of NiO under a polarizing microscope, have been confirmed, with the use of X-ray techniques, to come from the magnetic domain structure due to the existence of S-walls, whose crystallographic aspects are just as predicted in the preceding paper. From observed behaviours of S-domains in applied magnetic fields, the easy directions of magnetization within the easy plane (111) are determined to be turnrightup.eps[11\bar2], but not turnrightup.eps[1\bar10]. By observing the domain structures with Berg-Barrett method, the magnitude of spontaneous magnetostriction is obtained as | e x ' x ' - e y ' y ' |=(9±3)×10 -5 and e z ' x ' /( e x ' x ' - e y ' y ' )=-0.18±0.06, where the x '-axis is taken along the spin axis, and the z '-axis along [111].
