Abstract
A structure having a thin film magnetic layer sandwiched between a substrate and a surface layer is bombarded with ions. The ions impact the surface layer and cause atoms from the surface layer to be moved to implant into the magnetic layer. Thereby the magnetic characteristics of a region of the magnetic layer are altered, modified or destroyed.
