用非镜面偏振中子反射率观察了离子辐照后Co/Pt多层膜的远端磁性结构。虽然镜面和非镜面测量都表明，当样品处于剩余状态时，形成了人工畴结构，但在漫射散射中看到的谐振峰显示了与设计值一致的周期性的长程磁有序。当样品在平面上饱和时，这些峰被完全抑制，证实了它们在多层磁性图案中的起源。
The long-range magnetic structure in Co/Pt multilayers magnetically patterned by ion irradiation is observed by off-specular polarized neutron reflectivity. While both specular and off-specular measurements indicate the formation of an artificial domain structure when the sample is in its remanent state, resonant peaks seen in the diffuse scatter reveal long-range magnetic ordering with periodicity in agreement with the design value. These peaks are completely suppressed when the sample is saturated in plane, confirming their origin in the magnetic patterning of the multilayer.
