Filem berbilang lapisan Co/Pd dengan coercivity serenjang 2.2 kOe dan nisbah remanens (SQ) kesatuan telah disediakan oleh penyejatan rasuk elektron dalam vakum. Dalam imej MFM corak isyarat 4 kFRPI yang direkodkan menggunakan kepala MIG jenis cincin, banyak domain terbalik diperhatikan. Walau bagaimanapun, apabila filem itu dimagnetkan sepanjang filem arah normal menggunakan elektromagnet (H = -13 kOe), hanya beberapa domain magnet terbalik yang diperhatikan, yang konsisten dengan SQ = 1. Oleh itu, domain terbalik dalam corak isyarat telah diinduksi dalam proses rakaman. pemadaman dc juga dikaji dengan medan magnet cenderung kepada filem normal. Struktur domain adalah hampir sama apabila komponen serenjang medan dikekalkan malar manakala komponen dalam satah diubah, membayangkan bahawa komponen medan dalam satah tidak menyumbang kepada pembentukan domain terbalik. Didapati bahawa domain magnet terbalik mudah teraruh walaupun oleh medan magnet terbalik yang lemah digunakan di sepanjang filem normal. Oleh itu, walaupun kemungkinan medan kepala rakaman yang tidak mencukupi tidak dikecualikan, nampaknya lebih besar kemungkinan domain magnet terbalik dalam corak isyarat disebabkan oleh beberapa kesan pemadaman kepala MIG jenis cincin. Untuk medium berbilang lapisan Co/Pd dengan medan nukleasi negatif dalam gelung MH berserenjang, medan pembalikan yang lebih kuat diperlukan untuk mendorong domain magnet terbalik. Tiada domain magnet terbalik yang diperhatikan dalam imej MFM untuk corak isyarat 4 kFRPI dalam medium ini, menunjukkan bahawa medan nukleasi negatif berkesan untuk menyekat pembentukan domain magnet terbalik.

Abstract: A Co/Pd multilayer film with perpendicular coercivity of 2.2 kOe and remanence ratio (SQ) of unity was prepared by electron beam evaporation in vacuum. In the MFM image of signal patterns of 4 kFRPI recorded using a ring-type MIG head, many reversed domains were observed. However, when the film was magnetized along the film normal direction using an electromagnet (H = -13 kOe), only few reversed magnetic domains were observed, which was consistent with SQ = 1. Therefore, the reversed domains in the signal patterns were induced in the recording process. dc erasing was also studied with the magnetic field inclined to the film normal. The domain structures were almost the same when the perpendicular component of the field was kept constant while the in-plane component was varied, implying that the in-plane field component did not contribute to the formation of the reversed domains. It was found that reversed magnetic domains were easily induced even by a weak reversing magnetic field applied along the film normal. Hence, although the possibility of an insufficient recording head field was not excluded, it seemed more likely that the reversed magnetic domains in the signal patterns were caused by some erasing effect of the ring-type MIG head. For a Co/Pd multilayer medium with a negative nucleation field in the perpendicular M-H loop, a stronger reversing field was needed to induce the reversed magnetic domains. No reversed magnetic domains were observed in the MFM image for signal patterns of 4 kFRPI in this medium, indicating that a negative nucleation field was effective to suppress the formation of reversed magnetic domains.
