Abstract

We performed superconducting quantum interference devices and magnetic force microscopy (MFM) measurements on magnetic multilayer Co(60 Å)/Ni(90 Å)/Co(60 Å) nanoscale antidot samples. The antidot samples were fabricated on nanochannel glass substrates with different antidot diameters and the antidots ordered as a two dimensional hexagonal lattice structure. The results indicate that a self-organized domain structure is formed due to the pinning effect of the antidots. The strong uniaxial anisotropy of Co suppresses the shape anisotropy of the antidots and results in an uncommon domain structure. The field dependent MFM data reveal a reversal of magnetization.
