| 中文摘要 | Ferromagnetic nanocontact structures have attracted broad interest due to their potential applications in nanodevices as well as in the fundamental studies of domain wall location and controllable pinning, which are key factors to understand the physics of nanodevices based on these structures. In this paper, we investigated the distribution of domain wall in permalloy nanocontacts before and after magnetic field utilizing by Magnetic Force Microscopy (MFM). We find that the domain wall located in the vicinity of the nanocontact, which is not the exact contact position as supposed when a field of 5 kOe was applied. The mechanism behind such observation may mainly due to the energy equilibrium inside the sample. Moreover, mismatched nanocontact structures were designed and fabricated with domain wall pinned in the exact contact position, which suggests that the mismatched contact structures maybe an idea structure to investigate the interplay between the spin polarized current and the domain wall.
