초록

We have prepared FePtCu L10 bit patterned media, of which magnetic properties and microstructural details are obtained by direct measurement and observations. The patterning process on the continuous film induced a drastic changes in the coercivity, SFD, and angular dependencies. The origin of the changes are explained by micromagnetic simulations with the finite element models including the details of the microstructures.
