Abstract:
A method of manufacturing a multilayer film consisting of a stack of at least one primary soft-magnetic layer and at least one secondary non-magnetic layer on a substrate, comprising the steps of:providing a substrate on which said layers are to be deposited,providing a target having a single given composition for alternately depositing said at least one primary layer and said at least one secondary layer,sputtering to deposit said at least one primary layer by a reactive sputtering process in the presence of a first gas, andsputtering to deposit said at least one secondary layer by a reactive sputtering process in the presence of a second gas different from said first gas,characterized in that said first gas comprises an inert gas and no more than a first percentage of an active gas, and said second gas comprises a second percentage of active gas greater than said first percentage.
